Re: st: Poisson random number generator

[Roger Harbord <roger.harbord@bristol.ac.uk>]

I'd suggest Bobby Gutierrez's -genpoisson-, part of his excellent -gendist- 
package. Type -findit genpoisson- or -findit gendist- for details and to 
download. This uses plug-ins so is a lot faster than Hilbe & Linde-Zwirble's 
-rndpoi- and -rndpoix- from STB-28, though it only starts to matter if you're 
doing extensive simulations. Plug-ins require Stata version 8.1 or higher.

Interestingly, -findit random poisson generate- or -findit random poisson 
generator- fails to bring up gendist, perhaps because the package description 
contains "generation" and "generating" but not "generate"? But -findit random 
poisson generat- works. The lesson seems to be to omit word-endings that 
might change when using -findit- (or -search-, presumably).

Roger.
