   In that case, is the Stata FAQ (at http://www.stata.com/support/faqs/stat/panel.html)
 on which this code example is based also backward? 


I have not taken a careful look at that FAQ. It may be quite right and the user has not applied it correctly. In any case, if you compare two LLF values and come up with a negative Chi-square, something is wrong. Don't bother looking at the reported p-value in that case!
