Dear R users,

This is a basic question.

I want to fit a Weibull distribution. fitdistr(data, "weibull") works and it is a maximum likelihood fitting. Is it a good method ? Or is it better to write a function for the log-likelihood and the gradient and to use a numerical routine ?

Fitdistr works for uncensored data, but what can I use for censored (and uncensored) data ?

Thank you very much
