Dear all,
I am running an -xtnbreg- with bootstrapped standard errors:
xtnbreg DV var1 var2 var3 YearDummy1 YearDummy2 YearDummy3 YearDummy4,
fe vce(bootstrap)
However, the operation fails prompting the following error message:
--
insufficient observations to compute bootstrap standard errors
no results will be saved
r(2000);
--
As soon as I remove the YearDummies from the model everything is fine.
If anyone knows what I've done wrong in the first place (while using the
YearDummies), I'd be very grateful for some advice.
Many thanks in advance and kind regards,
Roman
