How to proceed "XTGLS" with OUTREG2?

Dear STATA Expert.

This is Jays.

I've been trying to make result table with outreg2, but I've encountered the message "the file....could not be opened"

My estimation model is "XTGLS"

When I try to use "XTGLS" rather than XTGLS, following order works,,,but...it won't work using "GLS"


outreg2 using c:\paper\Project3\regression\0802.xls, ctitle(FULL) bdec(3) tdec(5) adec(3) alpha(.001, .01, .05, .1) symbol(***, **, *, +) addstat(Wald Chi, e(chi2)) excel

Anyone could recognize the problem?

Thanks in advance.

Best,
J
