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...

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
