Re: st: autoregressive conditional poisson (ACP) model

[Jorge Eduardo Pérez Pérez <perez.jorge@ur.edu.co>]

To the best of my knowledge, Stata does not have a built in command to
estimate the ACP model (Heinen(2003): Modelling time series count
data: An autoregressive conditional Poisson model). I had to estimate
this model a while ago and I found difficult to program it in Stata
because it seems to me that Stata evaluates the likelihood function on
all the observations at once instead of doing it recursively, which is
the default for more time series oriented programs like Rats or
Eviews.

I wrote some code to estimate this model in Eviews which I can share
with you, without warranty...
