The CoxPH function is named for the Cox proportional hazards model, a statistical survival model. The function estimates coefficients by learning a set of explanatory variables.

The Cox proportional hazards model, proposed by David Cox in 1972, is a statistical survival model. The purpose of the model is to simultaneously explore the effects of several explanatory variables on survival.
