Cox proportional hazard regression is a regression model that is often used in survival analysis. Survival analysis is phrase used to describe analysis of data in the form of times from a well-defined time origin until occurrence of some particular even or end-point.

From the smallest AIC criteria obtained the best Cox proportional hazard regression model is Efron method.
