Description

Error




Random, unpredictable changes

Trend




Long-term directional patterns

Seasonality




Regular, repeating cycles

Strengths and Limitations

4. Survival Analysis for Customer Retention




Survival analysis focuses on time-to-event data, making it a great choice for understanding customer retention. Unlike time series models, which examine sequential patterns, survival analysis zeroes in on the timing of specific events, like customer churn. Originally developed for medical studies, this method has been adapted for predicting customer behavior.

The Cox Proportional Hazards Model




The Cox Proportional Hazards Model is a widely used approach in survival analysis, particularly for predicting customer lifetime value (LTV). This semi-parametric model is especially effective at dealing with censored data - data from customers who haven't yet churned - providing a more complete picture of retention trends.

Real-World Performance




In the telecommunications industry, the Cox model demonstrated 85% accuracy in predicting customer churn, allowing companies to take action before losing customers . This level of precision enables businesses to implement retention strategies that are both timely and effective.
