Introduction

I. INTRODUCTION

Customer churn analysis is the process of examining customer data to understand why customers stop using a product or service. It involves analyzing customer behavior, identifying patterns, and developing strategies to reduce customer churn. The goal of customer churn analysis is to retain customers and increase customer loyalty. Some common metrics used in customer churn analysis include customer retention rate, churn rate, and customer lifetime value. By analyzing these metrics, businesses can identify the factors that contribute to customer churn and take steps to address them. Customer churn analysis often involves using predictive models to identify customers who are at risk of churning. These models use historical data to predict which customers are most likely to stop using a product or service. Once at-risk customers have been identified, businesses can develop targeted retention strategies to keep them engaged. These strategies might include personalized offers, improved customer service, or product improvements. In addition to reducing customer churn, customer churn analysis can also help businesses identify new growth opportunities. By analyzing customer behavior, businesses can identify new markets or products that might be of interest to their customers. Overall, customer churn analysis is a critical process for any business that wants to retain customers and grow its customer base. By understanding why customers leave and taking steps to keep them engaged, businesses can improve customer loyalty and drive long-term growth.

3. Analysis of customer churn prediction in the telecom industry using decision trees and logistic regression: lonu? Brându?oiu, Gavril Toderean, Horia, (2021).

Customer churn is a major challenge for telecom companies as it leads to a loss of revenue and market share. Customer churn prediction using decision trees and logistic regression is a common approach to identify factors that contribute to customer churn and develop strategies to retain customers. Decision trees are a powerful tool for analyzing customer churn prediction as they can capture non-linear relationships between variables and help identify key drivers of customer churn. Decision trees split the data into subsets based on the values of predictor variables, creating a tree-like structure that shows how different variables interact to influence customer churn.

Logistic regression is another commonly used approach for customer churn prediction. It models the relationship between customer churn and predictor variables by estimating the probability of churn based on the values of these   variables. Logistic regression allows for the identification of significant predictors of churn and the calculation of their impact on the likelihood of churn. The telecom industry generates large amounts of data that can be used for customer churn prediction.

Variables that can be used for churn prediction include demographic information, usage patterns, and customer satisfaction ratings. By analyzing these variables using decision trees and logistic regression, telecom companies can develop targeted retention strategies that focus on the key drivers of customer churn. Overall, customer churn prediction using decision trees and logistic regression is an effective method for telecom companies to identify factors that contribute to customer churn and develop targeted retention strategies.
