Re: st: Survival Analysis: How to solve the problem of endogeneity of an explanatory variable

["Bartus Tamás" <tamas.bartus@uni-corvinus.hu>]

Dear Ingrid,
 
If you find the assumption of lognormal distribution realistic in your resarch, you might check the following
presentation:
 
http://www.stata.com/meeting/germany12/abstracts/desug12_bartus.pdf 
 

You might also be interested in the new features of Stata 13.1 which were advertised recently on the list.
 
 
 
(The above presentation does not deal with multispell data but I currently work on this extension)
