Taco et al,
I think I've found a way. Anthony Phan has written a brilliant stats package
for Metapost.
http://www-math.univ-poitiers.fr/~phan/statsmac.html
I think (haven't tried yet) I can select a number at random from the uniform
distribution on [0,1], then use one of Anthony's functions such as:
poissonicdf(expr p, lambda). Inverse cumulative distribution function of
P(lambda).
See Anthony's manual at:

Hi,
Does anyone have any strategies for drawing random numbers from
various statistics distributions in Metapost? For example, say,
drawing 100 random numbers from a beta distribution?
Assuming you are using mkiv: create a lua function and use its
calculated results to create the metapost code. Metapost only knows
about uniformdeviate and normaldeviate, and metapost is not a good
language to program mathematics in.
Best wishes,
Taco
