Abstract

Survival analysis is one of the most used statistical methods in medical research. While death or recurrency of illness called as failure in medical research, in subscription based business, loss of consumer (churn) can be taken as failure. Consumer database includes data about the start and end of the usage period of products or services. This information is used to construct the model in order to gain new consumers and to determine new marketing strategies. Survival models are one of the best methods to examine the consumer database. In this study, it is shown that semi-parametric and parametric methods can be used to analyze consumer database by using information about credit card holders.
