Hello there, I am a first time Stata user and am having a few problems. I already searched in this forum for a few hours but could not find answers to my problems.

I am running a panel data analysis on the effects of board diversity on firm performance over the time period from 2007-2017. I also include interaction terms in the analysis. All in all I have 18,354 observations and 1,712 companies.
Since I have missing values, I decided to do multiple imputation (due to the fact that my dataset is a panel, I reshape and impute in the wide format)
Code:
reshape wide y x1 x2 x3 x4 x1*x2 x1*x3 x1*x4, i(ID) j(year)
mi set wide
mi register imputed x12007 x12008 etc.
mi impute mvn x12007 x12008 etc.
reshape long y x1 x2 x3 x4 x1*x2 x1*x3 x1*x4, i(ID) j(year)
The multiple imputation works perfectly fine. After that, I test statistical assumptions (testparm _Iyear*; xttest3; kdensity) which indicate that I have to control for autocorrelation, heteroskedasticity and non-normal distribution. As far as I understand, the -xtreg vce(cluster ID)- function is perfect to use in my case.
To test whether to use fixed or random effects, I considered doing the Hausman test, but I cannot use the hausman test with robust standard errors. Thus I want to try the xtoverid command which is written by stata users:
Code:
mi estimate: xtreg y x1 x2 x3 x4 x1*x2 x1*x3 x1*x4, fe vce(cluster ID)
estimates store FE
mi estimate: xtreg y x1 x2 x3 x4 x1*x2 x1*x3 x1*x4, re vce(cluster ID)
estimates store RE
xtoverid
However, when I use it, it just says: xtoverid works only after xtreg, xtivreg, xtivreg2 or xthtaylor; last estimates not found

I also tried the xtoverid command without multiple imputation
Code:
xtreg y x1 x2 x3 x4 x1*x2 x1*x3 x1*x4, fe vce(cluster ID)
estimates store FE
xtreg y x1 x2 x3 x4 x1*x2 x1*x3 x1*x4, re vce(cluster ID)
estimates store RE
xtoverid
which worked fine and which said that I should use fixed effects.

Now what should I do?
I know that the hausman test has to be slightly adapted after multiple imputation
Code:
mi estimate, post: xtreg y x1 x2 x3 x4 x1*x2 x1*x3 x1*x4, fe
estimates store FE
mi estimate, post: xtreg y x1 x2 x3 x4 x1*x2 x1*x3 x1*x4, re
hausman FE
but I didn't find anything similar for the xtoverid command. Does anyone know how to handle the situation?

I would appreciate your help a lot! Thanks in advance!
