An R tutorial on performing logistic regression estimate. The R output of the logistic regression model is presented in figure 2. First, logistic regression predicts the occurrence probability of customer churn by formulating a set of equations, input field values, factors affecting customer churn and the output field (Ahn et al. Since churn is impacted by various factors and the factors differ for each customer, we would go ahead by modelling these complex behaviours with the power of mathematics and statistics! We use machine learning techniques like Random forest, XGBoost, Logistic regression, etc. However, PCA regression may not generate good churn samples if a dataset is nonlinear discriminant. 13 minute read.

Churn is one of the biggest threat to the telecommunication industry. Just counting will most likely not be sufficient though, you will need to analyze the content of the e-mail, audio from the conversations with customer care, web behavior and perhaps even social network analysis. Churn Prediction, R, Logistic Regression, Random Forest, AUC, Cross-Validation. LR is a predictive analysis used to explain the relationship between a dependent binary variable and a set of independent variables. Customer Churn Analysis: Using Logistic Regression to Predict At-Risk Customers For predicting a discrete variable, logistic regression is your friend. The logistic regression establishes group of equations (model), and relates each kind of probability of the input field value with probability of output field[5]. Logistic Regression is one of the most used machine learning algorithm and mainly used when the dependent variable (here churn 1 or churn 0) is categorical.
