Dear listusers,
When I run multivariate regression, the F or chi2 model statistic has been
reported as missing for some models. The Stata help menu says "the model
that you estimated has its F or chi2 model statistic reported to be
missing. Stata has done that so as not to be misleading, not because
there is something necessarily wrong with your model". But I want to
understand the mechanism behind this problem. I suspect it might be due
to the lack of LHS vars' variation or lack of statistical power. Does
anybody have experienced the same problem and have some thoughts to share?
What kind of consequence will this cause? Does it affect the
interpretation?
Many thanks,
Ying
