Hi all,
I would be very grateful if someone could give a hint on the following.
I have a panel data set and, when using the hausman test, I do not get a useful result (chi2 is negative). I know about the command suest. But to use suest the estimation must have been undertaken using a "score()" option. But as far as I can see this "score()" option is not defined for "xtreg".
Any help is very much wellcomed.
Thank you.
Paula
