I am running a fixed-effects time-series negative binomial regression
-xtnbreg- . After running the command, I receive this message:
initial values not feasible
r(1400);
I click on r(1400) and it says:
error . . . . . . . . . . . . . . . . . . . . . . . . Return code 1400
numerical overflow;
You have attempted something that, in the midst of the necessary
calculations, has resulted in something too large for Stata to
deal with accurately. Most commonly, this is an attempt to
estimate a model (say with regress) with more than 2,147,483,647
effective observations. This effective number could be reached
with far fewer observations if you were running a frequency-weighted
model.
Random effects works but I would like to run a fixed-effects model. Is
it still possible?
Thank you.
