In this chapter you will learn about the problems addressed by HR analytics, as well as will explore a sample HR dataset that will further be analyzed. You will describe and visualize some of the key variables, transform and manipulate the dataset to make it ready for analytics.

Introduction and overview

Finding categorical variables

Observing categoricals

Transforming categorical variables

Encoding categories

Getting dummies

Descriptive statistics

Correlations in the employee data

Percentage of employees who churn

Introduction to HR Analytics

This chapter introduces one of the most popular classification techniques: the Decision Tree. You will use it to develop an algorithm that predicts employee turnover.

Predicting employee turnover

Here, you will learn how to evaluate a model and understand how "good" it is. You will compare different trees to choose the best among them.

Employee turnover data

Di antara semua domain bisnis, SDM masih yang paling sedikit mengalami disrupsi. Namun, perkembangan terbaru dalam alat dan teknologi pengumpulan serta analisis data memungkinkan pengambilan keputusan berbasis data di semua dimensi, termasuk SDM. Kursus ini akan memberikan dasar yang kuat untuk mengelola data karyawan dan mengembangkan model prediktif untuk menganalisis perputaran karyawan.
