Panel Data and Studentized Residuals

[Jaweriah Abdullah]

I have a panel data set and am need to check the studentized residuals (or internally studentized residuals).
I use the command given below

xtreg lny lnar lnlab lnam lnfer lntract lnra lnirr lnlab2 lnfer2 lnam2 lntract2 lnar2 lnra2 lnirri2 lnlabtime lnfertime lnamntime lntracttime lnartime lnratimed lnirrtime lnlabam lnlabtract lnlabfer lnlabar lnlabra lnlabirr lnfertam lnfertract lnferar lnferra lnferirr

However when I proceed to use the command
predict rstudent, rstudent

I get the error
predict rstudent, rstudent
option rstudent not allowed
r(198);

Please let me know what I am doing wrong and what is the correct step

The rstudent option can be specified with simple regression, not panel regression. One workaround can be to estimate LSDV model, i.e. creating dummy variables for each cross-sectional unit and then use the rstudent option.
