Hello
I would like to compare the results obtained with a classical non parametric proportionnal hazard model with a parametric proportionnal hazard model using a Weibull.
How can we obtain the equivalence of the parameters using coxph(non parametric model) and survreg(parametric model) ?
Thanks Virginie
In the Design package look at the pphsm function that converts a survreg Weibull fit (fitted by the psm function which is an adaptation of survreg) to PH form.
