Hi,
I use panel regression regression with robust std error but STATA reports the following messages;
1.The Wald chi2 model statistic has been reported as missing.
2.corr(u_i, X) = 0 (assumed) >> Is there any problem with the model?
3.sigma_u and rho are zero
4.when command e(r2_a) following outreg2, STATA reports to check eret list and I found there's no e(r2_a) in the list. What should I do If I want the Adjusted R2
Commands and results are in the attachment.
Many Thanks
Sara
