Weibull is an obvious key word here and -findit weibull- points to various resources, including -weibullfit- from SSC. Did you try that? But the cdf of y that is a two-parameter Weibull is one line of Stata gen F = 1 - exp(-((y/b)^c)) -- where b is a scale parameter and c is a shape parameter -- so it is not clear to me why you seek a package for it. Your parameterisation may differ, but the formula is still simple. -weibullfit- fits, and -qweibull- and -pweibull- offer standard diagnostic plots for univariate fitting.
