Re: st: SPSS vs STATA for panel data analysis with binary and categorical outcome variables

["Rodrigo A. Alfaro" <ralfaro76@hotmail.com>]

For sure Stata will give you more options than SPSS and there is a huge 
community that is working with Stata, with similar problems to solve as you. 
In the reference manual set you will find a specific book that explain the 
panel data commands, take a look it at 
http://www.stata.com/bookstore/xt.html. Many econometrics textbook include 
Stata examples, but you can use the web for a introduction to the topic:
http://dss.princeton.edu/online_help/analysis/panel.htm, 
http://www.ats.ucla.edu/stat/stata/stat130/longitud.htm or 
http://www.ats.ucla.edu/stat/stata/library/3uk_paneldata.htm. Rodrigo.
