st: arpois and mean effects

["Richard S. Conley, PhD" <rconley@polisci.ufl.edu>]

Dear Colleagues,

Can anyone tell me an easy way to calculate mean effects (as in "mfx" 
for regular poisson) for autoregressive poisson (par) or the "arpois" 
command in Stata? 

If I use "mfx" in the post-estimation command, Stata tells me the 
subroutine is not available for nl (nonlinear) estimates.

Many thanks,
