The goal of this project was to produce a predictive model that scores a policyholder’s likelihood to churn within a given time window. Mutual of Omaha understood policyholder persistence through an actuarial lens which is limited to variables that the industry understands well and to probability theories and statistical techniques that have a long history. Machine learning driven model discovery, by contrast, avails itself of a wider set of predictive variables and leverages the unusual size of datasets in modern enterprises to validate the patterns it discovers.
