Dear Statalisters,
I estimated the following Model in Stata:
xtmixed cr5 firmsize firmrisk firmrisk_sqr firmperformance regulation
shareholderprotection || country: || industry: , variance
yielding the followng results stated at the end of this Mail.
Could you give me any advice how the LR test? ( LR test vs. linear
regression: chi2(2) = 56.66 Prob > chi2 = 0.0000) or where
to find information on this?
Best regards
Christian
