st: perform Poisson simulations

[Zhiqiang Feng <zf2@st-andrews.ac.uk>]

Dear all,

I try to do Poisson simulations using STATA.

Firstly I fit Poisson model with the observed values.

Poisson y x1, x2, ...xn

predict yhat, n.

The I try to derive Poisson random numbers using the predicted values 
as means.

y_random=??(yhat)

However, I can not find a way to derived Poisson random numbers in 
STATA. I do find a similar function in SAS (ranpoi) though. I also 
know there is such a function in GLIM.

I am grateful if someone could make some suggestions.

thanks,

zhiqiang
