Well, at the end of the day, it is easy enough to call R with the
-shell-/-winexec- commands, generate with the rexp() command there and to
export with the foreign-package back to Stata. For this reason, I have never
bothered to look at Stata`s own commands: at the time, it also seemed
unclear to me why one would write things like "invnormal(uniform())" only to
generate normal random numbers. Seems horribly complicated...

Subject: st: exponential distribution
Does anyone know how to create an exponential
distribution with a mean of 1 to use as random
numbers? I believe it's a tweak on exp=-ln(uniform()),
but am not sure.
Thanks,
jon
