The asymptotic...
One majoraspect in medical research is to relate the survival times ofpatients with the relevant covariates or explanatory variables.The proportional hazards model has been used extensively in thepast decades with the assumption that the covariate effects actmultiplicatively on the hazard function, independent of time.If the patients become more homogeneous over time, say the treatmenteffects decrease...
