Multivariate Logistic Regression - Telecom Churn.txt

Let's now look at the process of building a logistic regression model in Python.

 

You will be looking at the telecom churn prediction example. You will use 21 variables related to customer behaviour (such as the monthly bill, internet usage etc.) to predict whether a particular customer will switch to another telecom provider or not (i.e. churn or not).

 

Problem Statement
You have a telecom firm which has collected data of all its customers. The main types of attributes are:

Demographics (age, gender etc.)
Services availed (internet packs purchased, special offers taken, etc.)
Expenses (amount of recharge done per month etc.)
 

Based on all this past information, you want to build a model which will predict whether a particular customer will churn or not, i.e. whether they will switch to a different service provider or not. So the variable of interest, i.e. the target variable here is ‘Churn’ which will tell us whether or not a particular customer has churned. It is a binary variable: 1 means that the customer has churned and 0 means the customer has not churned.
