Hi, I'm having troubles generating 2 new variables with my data. I have the following variables: ID; E01-E12 where E01 =3 indicates that i is enrolled in a 4 year college in January, and E05=2 means that he is enrolled in a 2 year college in may. I want to generate a 2 new variables Total_2_year that is the total number of month that i is enrolled in a 2 year college and total_4_year that is the total number of month that i is enrolled in a 4 year college. What is the best way of doing this? My first attempt was this <code> *Generates vectors of total months enrolled in college gen total_2_year = 0 gen total_4_year = 0 gen total_none = 0 forvalues month=1/9 { if 511200`month'==3 then total_4_year==total_4_year+1 if 511200`month'==2 then total_2_year==total_2_year+1 if 511200`month'==1 then total_none==total_none+1 if 511200`month'==-4 then total_none==-4 if 511200`month'==-4 then total_2_year==-4 if 511200`month'==-4 then total_4_year==-4 } </code> but i get only zeros... :_( Thanks a lot -Ignacio * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
