You cut your own words and mine, which doesn't help anyone trying to follow the thread. -findit weibull- turns up lots of links; I haven't read them all, so I have no way of knowing whether they are all useless as far as you are concerned. You asked "Is there a Stata package to compute the cumulative distribution of a two-parameter Weibull distribution that I am not aware of?" and I told you how to compute a cdf. Please forgive me for not knowing that when you wrote that you actually meant computing a P-value, which is to me a different problem. I now am not sure quite what P-value you have in mind, but if you want to test goodness-of-fit you will (contrary to what you imply) find a test in -weibullfit-.
