st: Right truncated Poisson for panel estimators

The dependent variable is a daily count of the number of
clinically-meaningful adverse opioid-related symptoms (e.g., fatigue,
drowsy, concentration) right-truncated at <= 3 on each day and the data
is for 3 days.

Would you please advise on how to estimate this model with a random
intercept and random coefficients for the independent variables time and
amount of opioid consumed?

Relatedly, I would then like to estimate the above model
(right-truncated) specified as a population-averaged model in order to
used the results as input into an economic model.  Would you please
advise on how to accomplish this? I believe LIMDEP has such capabilities
but I am rather reluctant to re-learn this program in the middle of a
project.

Finally, if I must use LIMDEP to estimate the model, can I input the
LIMDEP estimates into STATA in order to use the superior STATA
facilities such as statsby (I've got 8 surgical-type dummies, gender,
and 3 age categories by which to estimate predicted values).

Thank you,
Mark
