variables as a multiplier of a common baseline hazard function,h0(t). The hazard function is the nonparametric part of the Cox proportional hazards regression function, whereas the impact of the predictor variables is a loglinear regression. For a baseline relative to 0, this model corresponds ...

The Cox PH model assumes that predictors act multiplicatively on thehazard function but does not assume that the hazard function is constant (i.e.,exponential model), Weibull, or any other particular form. The regressionportion of the model is fully parametric; that is, the regressors are ...
