st: comparing coefficients across menbreg models

[Steve <drlead@prodigy.net.mx>]

I have two count outcomes each with two waves in the same subjects 
modeled with -menbreg-.  The predictors are the same for both outcomes.  
I want to compare the coefficients of the same predictors between the 
two models but I can't use the combination of -estimates store- followed 
by -suest- and -test- to compare them because -menbreg- does not 
generate score predictions.
Is there another way of comparing coefficients of the same variables 
across mixed negative binomial models?
