parametric proportional hazard regression
There is some generalized F code (which would include many other parameteric survival models as submodels) at this page. The R package seems somewhat non-standard in terms of installation and I have not tried it: http://www.math.mun.ca/~ypeng/research/

I am new to the field of survival analysis and my first text read on that topic is Franses/Paap, Quantitative Models in Marketing Research, Chapter 8. There the kind of models I describe are the standard proportional hazard models. But also in Internet I find texts which say something about parametric PH models, where the baseline hazard can take some specific form! See for instance: http://www.weibull.com/AccelTestWeb/proportional_hazards_model.htm The second part reads "parametric PH models" and there is an example with the Weibull baseline distribution. The log-likelihood is derived, too. The same could be done with the other distributions I mentioned (lognormal, loglogistic, exponential). Anyway, if you say these models are untraditional, then maybe there is also no R-function for them... In that case I'll write a R-code myself to fit them using ML. Kind regards, Valentin
