math.ucsd.eduThe Cox Proportional Hazards model is a linear model for the log of the hazard ratio One of the main advantages of the framework of the Cox PH model is that we can estimate the parameters without having to estimate 0(t). And, we don’t have to assume that 0(t) follows an expo-nential model, or a Weibull model, or any other particular
