Title: Estimating Attrition Using Survival Analysis


Retention is an important factor that impacts both profit and growth of insurance companies. Conventional retention analysis, such as logistic regression, does not distinguish two types of attritions: mid-term cancellation and end-term nonrenewal. In this presentation, We propose to use survival analysis to estimate attrition and retention. Compared with conventional methods, the approach has three advantages: 1) it addresses not only whether the policy will leave but also when it will leave; 2) it analyzes mid-term cancellation and end-term nonrenewal sequentially, and therefore provides a dynamic insight of retention, which improves the static view derived  from snapshot data; 3) it can take into account time-varying macroeconomic variables, and would help researchers to understand how insurance retention is impacted by the broader economic environments. A case study illustrates the technique from creating the panel data required by survival analysis to interpreting the model results.
