Hello,
I have a question regarding the XTABOND2 command. I'm attempting to run the
following model:
xtabond2 y l.y x1 x2 x3 , robust twostep ivstyle(l.y x1 x2 x3)
but get the following message:
repeated time values within panel
r(451);
I've rechecked my data with the DUPLICATES command and found no duplicated
observations based on my TSSET criterion.
Does anyone have any suggestions regarding the error I'm committing?
Thanks
Ed
