Asunto: Re: st: re: other ways of dealing with endogeneity other than IV?
Kit et al.--
A fixed-effects model deals with one very specific type of endogeneity
due to omitted variables that vary only across groups in i() and not
within. Hence the discussion of -xtreg- in
http://www.stata-journal.com/article.html?article=st0136
But it sounds like Luis Ortiz needs survival analysis tools, not
-xtreg-, so he might like to read some of the references in this list:
