Hello Ekaterina, I have developed a solution which works on the small example data set given in Oliver Jones' response. My code may not look very professional as I have just started using 'foreach'. I would very much appreciate some feedback on my code. Regards, Pathmes *************** example code begins ************************** version 8 clear all set obs 7 gen byte id = _n gen byte sex = 1 replace sex = 0 in 4/7 label def lbl_sex 0 "male" 1 "female" label values sex lbl_sex gen int income = 7 replace income = 10 in 3 replace income = 0 in 4 replace income = 7 in 5 replace income = 9 in 6 replace income = 11 in 7 list * I have just copied Oliver's code sort sex gen idm=_n if sex==0 * idm is just a unique number for each male gen fa=. label variable fa "Number of females with higher income" gen fb=. label variable fb "Number of females with lower income" gen fe=. label variable fe "Number of females with equal income" * The variables fa, fb & fe are generated individually for each male in the following loop quietly{ foreach n of numlist 1/4 { egen int feabove = rank(income) if sex==1 | (sex==0 & idm==`n'), field replace fa= feabove-1 if idm==`n' drop feabove egen int febelow = rank(income) if sex==1 | (sex==0 & idm==`n'), track replace fb= febelow-1 if idm==`n' drop febelow replace fe=3-( fa+ fb) if idm==`n' } } * Converting the numbers to proportions gen fap=fa/3 label variable fap "Proportion of females with higher income" gen fbp=fb/3 label variable fbp "Proportion of females with lower income" gen fep=fe/3 label variable fep "Proportion of females with equal income" **************** example code ends *************************** * * 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/
