Valentin,

Have you tried survreg() in the Design library?

Regards,

Subject: [R] parametric proportional hazard regression

Dear all,

I am trying to find a suitable R-function for parametric proportional hazard regressions. The package survival contains the coxph() function which performs a Cox regression which leaves the base hazard unspecified, i.e. it is a semi-parametric method. The package Design contains the function pphsm() which is good for parametric proportional hazard regressions when the underlying base distribution is "weibull" or "exponential". But what if I need a parametric proportional hazard model with the other "usual" distributions like '"gaussian"', '"logistic"', '"lognormal"'and '"loglogistic"?

Thanks a lot for your support!
