Every year a lot of companies hire a number of employees. The companies invest time and money in training those employees, not just this but there are training programs within the companies for their existing employees as well.

The aim of these programs is to increase the effectiveness of their employees. But where HR Analytics fit in this? HR Analytics. Human resource analytics HR analytics is an area in the field of analytics that refers to applying analytic processes to the human resource department of an organization in the hope of improving employee performance and therefore getting a better return on investment.

HR analytics does not just deal with gathering data on employee efficiency. Instead, it aims to provide insight into each process by gathering data and then using it to make relevant decisions about how to improve these processes. Attrition in HR. Attrition in human resources refers to the gradual loss of employees over time.

In general, relatively high attrition is problematic for companies. HR professionals often assume a leadership role in designing company compensation programs, work culture and motivation systems that help the organization retain top employees.

How does Attrition affect companies? We will discuss the first question here and for the second question we will write the code and try to understand the process step by step.

Attrition affecting Companies. A major problem in high employee attrition is its cost to an organization. Job postings, hiring processes, paperwork and new hire training are some of the common expenses of losing employees and replacing them.

Additionally, regular employee turnover prohibits your organization from increasing its collective knowledge base and experience over time. This is especially concerning if your business is customer facing, as customers often prefer to interact with familiar people. Errors and issues are more likely if you constantly have new workers. Hope the basics made sense.

For this exercise, we will try to study the factors that lead to employee attrition. This is a fictional data set created by IBM data scientists. We need to first check the data type of the features, why?

For this exercise, our aim is to predict the employee attrition and it is important to see which variables are contributing the most in attrition.

But before that we need to know if the variables are correlated if they are, we might want to avoid those in model building process. There are many continuous variables, we can have a look at their distribution and create a grid of pair plots but that would be too much code to see the correlation as there are a lot variables. Rather, we can create a seaborn heatmap of numeric variables and see the correlation. The variables which are not poorly correlated i. From the above heat map we can now see which variables are poorly correlated and which ones are strongly correlated.

Now replace other categorical variables with dummy values. We have our final dataset. We now have to start modelling- Predicting the Attrition.Not surprisingly then, the broader application of predictive modeling across the enterprise along with the emergence of HR Analytics is leading organizations to ask how HR can start using data to predict and ultimately reduce employee turnover. The goal of this primer is to provide the basic guidelines and starter code you need for two essential yet powerful techniques for predicting employee turnover.

The code is in R, the premier open-source tool for data manipulation, analysis, and visualization. The specific goal here is to predict whether an employee will stay or voluntary leave within the next year. You can think of this data as historical data which tells us who did and who did not leave within the last year. Our initial step is to describe and visualize our data. Then, we will develop two different kinds of predictive models.

The first of these is a logistic regression model. Logistic regression models predict the likelihood of a categorical outcome, here staying or leaving. The second kind of model is known as a decision tree or a classification tree. A decision tree is essentially a set of rules for splitting the data into buckets to help us predict whether the employees in those buckets will end up in one group staying or another group leaving. In both cases, we are classifying into just two possible groups.

After we lay the foundation for model development, we then explain how to evaluate model quality using overall model accuracy and the Receiver Operator Curve ROC. While there are certainly more complex techniques for predicting turnover, logistic regression and decision trees both work extraordinarily well. Moreover, they are comparatively easy to implement and, most importantly, easier to interpret and explain.

This is critical when translating modeling insights into action. This dataset has 8 different variables like those that you might have in your own HR data. After downloading the datarun the following code to set up the packages you will need.

Like everything with open-source R, these packages are totally free. We would still need this information though to map our results to our workforce. The table and histograms give us a look at the distribution. When we use the aggregate function to break down the probabilities by performance group, we can see turnover is much higher for the high performance group.

Definitely major issues for our female employees v. If this was your company, alarm bells should be going off and the investigative needs would start with more descriptive analyses and some additional, focused modeling. Those in Sales are much more likely to leave.

There might a slightly elevated difference for females in the sales group, but nothing huge. Any significant interaction should be fleshed out in our later modeling anyway so we can move on. It will be more informative to see how those ages breakdown when we take that into account.

As a reminder, the black lines within each box represent the median. This means there is a strong relationship between Age and Role, although the difference would not likely be so pronounced with data from a real company. Regardless, if we only retained one of these variables in the model, we might mistakenly attribute turnover differences to age when they are instead more related to role, or vice versa.

Still, given that age is extremely skewed, we should be concerned about including it in our logistic regression model as is. This plot suggests a steady increase in turnover rate between age 34 and 46, a generally elevated rate until 58, and followed by a steep dropoff.

We can see three distinct pieces, corresponding tightly to the role. Given the huge differences in salary, we should find another way to represent salary that is more meaningful across the roles.

By this new metric, salaries lower than the median of the relevant role will be negative, those higher than the median will be positive.The purpose of analytics is not just to understand why you lost an employee but how you can prevent from losing one. Insight is the soul of Predictive Analytics. How organizations create and use data is changing the process of life, work or leisure.

This webinar blog focuses on how smarter organizations are adopting Predictive Analytics and rightly so! It also dwells on the following topics:. BI is basically what is happening to your business. It is used for visibility. Data Warehousing and visualization dashboards are enablers of BI. While BA is why it is happening; what is likely to happen in future. It is used for investigation, prediction and prescription. This extends beyond measuring and describing the past to predicting what is likely to happen and optimizing what should happen.

Predictive Analytics is the analysis of data by using statistical algorithms and machine-learning techniques to identify the likelihood of future outcomes based on historical data. Predictive Analysis helps analyze past business performance in order to gain insight that can drive business decisions and actions.

According to Forbes, the top objective for between two-thirds and three-quarters of executives is to develop the ability to model and predict behaviours to the point where individual decisions can be made in real time, based on the analysis at hand.

Predictive Analytics is no longer the sole domain of data scientists. Some of the major domains using Predictive Analytics are banking, e-commerce, HR, retail, transport, healthcare, IT industry among many others.

Churn or attrition is when your customers reduce their usage or completely stop using your products or services.

Predictive Attrition Model: Using Analytics to predict Employee Attrition

They leave your brand and might shop with your competitor. Churn prediction is a common application where the number of churners is typically small compared to the number of customers that stay.

From predicting attrition among high performers to predicting how compensation values will pan out, an HR can benefit enormously from Predictive Analysis :.

Relying on just a few metrics to evaluate employee performance. Smart employees can play with the system. Assessing employees only on simple measures such as grades and test scores, which often fail to accurately predict success.

Using analytics to hire lower-level people but not when assessing senior management. Analyzing HR efficiency metrics only, while failing to address the impact of talent management on business performance. Predictive Analysis can precisely identify the value of a 0.

Sprint has identified the factors that best foretell which employees will leave after a relatively short time.Employee attrition is predictable under stable circumstances, wherein a set pattern can be deduced from certain parameters influencing the employee and the organization at all times.

Some of these parameters could be foreseeable such as retirement age or unforeseeable such as company performance, external funding, management shakeup etc. However, who is going to leave, when and why, can be answered based on analytical models developed as a result of data analysis.

Through predictive algorithms, companies gain better understanding and can undertake preventive measures for employee attrition.

Turnover: Predicting Attrition

Occasionally, other parameters like performance over the years, pay raise, work batch, educational institution are also taken into consideration. Various statistical and machine learning algorithms are designed to construct the predictive models. For models involving multiple parameters, the decision trees tend to become very large and complex.

Besides, these models aim to provide good predictability. However, seamless implementation depends on choosing the right model.

Thus, different models are chosen based on the aforementioned parameters, data availability, budget, computational power and the requirements of decision makers.

For example, in one organisation, a model using artificial neural network may provide better predictability than a decision tree model, but a decision tree model may be easier to understand and implement at a lower cost.

Thus, depending on the organizational contexts, different models have to be tried and evaluated before making the final selection. The output depends on the chosen model. However, the bottom line is to keep it simple enough for HR managers to understand and implement accordingly.

Changing the various factors help in assessing the impact of changes and making the right decisions. Predictive Attrition Model helps in not only taking preventive measures but also into making better hiring decisions. Moreover, HR can use the employee data to predict attrition, the possible reasons behind it and can take appropriate measures to prevent it.

We live in a data-driven world — from something as trivial as weather updates to complexity behind GPS navigations, data is constantly being generated every second in every field, which leaves us to decide how to turn it around for our advantage in our respective domains.

More and more data is being captured and stored across industries and this is changing society and how businesses work. How much did we spend on that marketing campaign? What is the loan default rate? How many employees left my company? Today, companies are involved in a digital transformation that enables the next generation of BI: Advanced Analytics AA.

With the right technologies and a data science team, businesses are trying to get an answer to a new game-changing question: What will happen in my business? This translates into more specific questions depending on the industry: How many products will we sell? How much should we spend on each marketing campaign? What is the predicted loan default rate? Which employees are about to leave? We are already seeing how AA is helping to increase profits in many companies. However, some businesses are late in the adoption of AA due to a lack of information about its power and all the ways it can be used, while others are trying to adopt AA but are failing for various reasons.

ClearPeaks is already helping many businesses to adopt AA, and in this blog article we will review, as an illustrative example, an AA use case involving Machine Learning ML techniques. The success of the digital transformation and AA adoption in any business depends on the participation of most of its departments. And, of course, HR departments are key to driving the deep cultural change required, recruiting employees with new capabilities, developing in-house training plans, and most importantly, retaining the most talented employees.

We cannot think of a better use case for this blog entry than one that will help companies along their AA adoption journey by keeping the talent making that adoption possible. Employee attrition refers to the percentage of workers who leave an organization and are replaced by new employees; a high rate of attrition in an organization leads to increased recruitment, hiring and training costs.

Not only is it costly, but qualified and competent replacements are also hard to find. Augustine, On average, organizations invest between four weeks and three months training new employees. Reducing attrition translates into consistent production, reduced recruiting costs, consistent customer contacts and the enhanced morale of the remaining employees.

We will use machine learning models to predict which employees will be more likely to leave given some attributes; such a model would help an organization predict employee attrition and define a strategy to reduce this costly problem.

With KNIME we can perform data extraction and transformation, feature engineering, as well as model training and evaluation.HR professionals prepare the Attrition report monthly or yearly to monitor and rectify the causes of attritions in the organizations.

Attrition means the reduction in the number of employees of an organization through resignation, retirement or death. The attrition rate means calculating the proportion of employees leaving an organization over a specific period. It is also known as employee turnover rate. A normal rate of attrition is expected in normal business operations. But a high rate of attrition leads to many problems and a lack of workforce. HR professionals design and implement company compensation programs and motivation systems to keep the employees happy and attrition rates low.

Keeping the attrition rates as low as possible helps to save money. You can save money spent on advertising for hiring, training and completing paperwork for new employees. Just enter the number of employees leaving and joining the organization in the respective cells and it will automatically calculate the attrition rate for you.

With this template, you can easily monitor the monthly attrition rate of your organization and take relevant measures to decrease them. Opening Balance: Opening balance of the employee count at the start of January.

If you have historical time-based data, you can use it to create a forecast. When you create a forecast, Excel creates a new worksheet that contains both a table of the historical and predicted values and a chart that expresses this data. A forecast can help you predict things like future sales, inventory requirements, or consumer trends. Information about how the forecast is calculated and options you can change can be found at the bottom of this article.

Create a forecast In a worksheet, enter two data series that correspond to each other:. For example, monthly intervals with values on the 1st of every month, yearly intervals, or numerical intervals.

The forecast will still be accurate. However, summarizing data before you create the forecast will produce more accurate forecast results. On the Data tab, in the Forecast group, click Forecast Sheet.

Forecasting in Excel using Linear Regression

In the Create Forecast Worksheet box, pick either a line chart or a column chart for the visual representation of the forecast.

In the Forecast End box, pick an end date, and then click Create. Excel creates a new worksheet that contains both a table of the historical and predicted values and a chart that expresses this data. You'll find the new worksheet just to the left "in front of" the sheet where you entered the data series.

If you want to change any advanced settings for your forecast, click Options. You'll find information about each of the options in the following table. Pick the date for the forecast to begin. When you pick a date before the end of the historical data, only data prior to the start date are used in the prediction this is sometimes referred to as "hindcasting".

Starting your forecast before the last historical point gives you a sense of the prediction accuracy as you can compare the forecasted series to the actual data.

However, if you start the forecast too early, the forecast generated won't necessarily represent the forecast you'll get using all the historical data. Using all of your historical data gives you a more accurate prediction.

If your data is seasonal, then starting a forecast before the last historical point is recommended. Check or uncheck Confidence Interval to show or hide it. Confidence interval can help you figure out the accuracy of the prediction. A smaller interval implies more confidence in the prediction for the specific point. Seasonality is a number for the length number of points of the seasonal pattern and is automatically detected.

For example, in a yearly sales cycle, with each point representing a month, the seasonality is You can override the automatic detection by choosing Set Manually and then picking a number. With less than 2 cycles, Excel cannot identify the seasonal components.

And when the seasonality is not significant enough for the algorithm to detect, the prediction will revert to a linear trend.
