Simple countplots and histogram plots of features can give us a general idea of how each feature is distributed. If nothing happens, download GitHub Desktop and try again. Many people signup for their training. This content can be referenced for research and education purposes. Using the pd.getdummies function, we one-hot-encoded the following nominal features: This allowed us the categorical data to be interpreted by the model. Interpret model(s) such a way that illustrate which features affect candidate decision In order to control for the size of the target groups, I made a function to plot the stackplot to visualize correlations between variables. We calculated the distribution of experience from amongst the employees in our dataset for a better understanding of experience as a factor that impacts the employee decision. Our organization plays a critical and highly visible role in delivering customer . In other words, if target=0 and target=1 were to have the same size, people enrolled in full time course would be more likely to be looking for a job change than not. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. The number of men is higher than the women and others. Question 3. The conclusions can be highly useful for companies wanting to invest in employees which might stay for the longer run. A tag already exists with the provided branch name. On the basis of the characteristics of the employees the HR of the want to understand the factors affecting the decision of an employee for staying or leaving the current job. Identify important factors affecting the decision making of staying or leaving using MeanDecreaseGini from RandomForest model. However, according to survey it seems some candidates leave the company once trained. The stackplot shows groups as percentages of each target label, rather than as raw counts. We achieved an accuracy of 66% percent and AUC -ROC score of 0.69. Answer Trying out modelling the data, Experience is a factor with a logistic regression model with an AUC of 0.75. If company use old method, they need to offer all candidates and it will use more money and HR Departments have time limit too, they can't ask all candidates 1 by 1 and usually they will take random candidates.
