It should be noted that those are not just wrappers like invcdf(
runiform() ), but seem to be efficient quick generators based on some
common numerical statistics algorithms. And they are almost compatible
with R -- the Stata functions miss an argument (length of the vector),
while Mata functions have one too many (# rows and # columns instead
of that length) :)).

I wonder if Stata Corp. has any feeling of how exactly faster those
functions are compared to cdf inversion. I am sure the comparisons of
accuracy and speed were performed before those functions were
released.
