Dear Nick,

If I use *, then I am getting the results for the poisson model and not nbreg. I had actually got the model working but somehow did not save my results. I though that I had used # operator then, but I am not sure.

Thanks,

Prabhu

You presumably want some other operator.

I am new to ml command. I am getting an error: Unknown
function (), when I run the following code for negative binomial count model. Is there any obvious error in the code which I seem to miss out.

The L function is -exp(lambda.ui).(lambda.ui)^yi/(yi)!

program define nbreg2
args lnf theta uu
quietly replace `lnf' = -exp(`theta')#`uu' + $ML_y1#(`theta'+ln(`uu')) - lnfact($ML_y1)
end
ml model lf nbreg2 (jdemh=price eff) ()
ml check
ml maximize
