Dear all,
I am trying to run a Zero inflated Poisson on an unbalanced Panel using the command line as suggested by the manual.
In my case the command line is
Poisson; Lhs=NOF_SITE; Rhs=One,MEMBERYE,PC,POP; Rh2=One,MEMBERYE,PC,POP; ZIP; Pds= _GROUPTI $
Unfortunately, the output shows first
Warning 246: Poisson/NegBin w/ panel. Cannot compute fn at current parms
and then there is the estimation of a Poisson regression with Random Effects.
I tried to use the ZIP without the Panel specification and everything seems ok. But, of course, I am interested in the ZIP with Panel Data.
Does anyone have any clue where I am getting wrong?
Thank you
Best
