[R] parametric proportional hazard regression

[Valentin Dimitrov]

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!
