Subject: st: Stata & LIMDEP comparison for count models

[jhilbe@aol.com]

I just saw your query. Apologies for the delay.

LIMDEP is a very complete package for modeling counts, but still lacks 
in certain areas, which Stata has. Stata, LIMDEP, and recently R offer 
for more count models than other software. They are in a league by 
themselves in
this respect.

There are a host of count models. I think all of the basic and perhaps 
not-so basic, count models are offered in
both Stata and LIMDEP. LIMDEP has a few more count models for panel 
data than Stata; eg random coefficient negative binomial, and offers 
the full range of truncated and censored Poisson and NB models. 
Official Stata does not  have censored count models, for example, but 
user authored censored count models can be downloaded from the SSC 
site. LIMDEP does not have various count models that are available as 
user created ado files; eg finite mixture models, quantile count 
models. In many respects it's a trade off.

LIMDEP may have a few more count models, but many are seldom used. 
Stata is a really very good package for modeling counts, and should be 
satisfactory for most needs. New models are being created by someone 
within
the Stata community all of the time.

Dear Statalisters, I  need to compare Stata and LIMDEP capabilities for 
count models.
Is there a good source where I can read about it ?
Thank you. Eugenia
