Alison -
I'm afraid your question is not specific enough. What model are you running
to get estimates of your coefficients? What random variable do you want to
get the cdf and/or pdf for? What distribution does it have under the assumed
model? Do you want to evaluate this cdf/pdf as a function prescribed by your
model over a range of values, or do you want to compute an empirical cdf or
pdf from data?

Subject: st: Cumulative Distribution Function
Hi:
I have a problem of getting the cumulative distribution function (cdf)
and probability density function (pdf). In particular I need to get the
cdf and pdf evaluated at the estimated coefficients (beta) and standard
errors (sigma). I realize there are the "cumul" & "kdensity" command in
stata, but those only allows a single variable, but I have more than one
variable.
Does anyone have a better idea of how to get cdf or pdf?
Thanks.
