I'm estimating a 2SLS model with two fixed effects, and I would like to include the estimated effect for just one of the effects in the output table, but I cannot figure it out. For example, the estimation code is:

ivreghdfe y = x1 x2 (x3 = x3IV), small absorb(FE1 FE2)

I am interested in the estimates for FE2, which has 4 levels. I have tried in the following code creating a variable from FE2 and looking at the values in the data, but some observations do not have estimates attached to them, so I am not sure what's going on there.

ivreghdfe y = x1 x2 (x3 = x3IV), small absorb(FE1 coeffs=FE2)

I've also tried

eststo clear
eststo: ivreghdfe y = x1 x2 (x3 = x3IV), small absorb(FE1 coeffs=FE2)
esttab, cells(b) indicate(coeffs) s(fixed N, label("fixed effects"))

and get the error "coefficient coeffs not found."

Any help is appreciated!
