Hi all.
I have Intercooled Stata 8.0. I am trying to estimate a fixed-effects model with 4,000 panels through 400 periods of time. I want to add dummies by panels and time. I also want to cluster observations by panels.
I tried with:
xi: areg work i.month anychildren pregnant [pweight=weight], absorb(panelid) cluster(panelid)
but Stata gives me the following error message
"no room to add more variables due to width
An attempt was made to add a variable*"
Any suggestions? Thanks!!!
