Briefer yet: gen min=mininc1*500+mininc2*1000+mininc3*1500 which also traps the missings Nick cautions about. hth, Jeph Nick Cox wrote:

A variation on the same idea:gen min = 500foreach v in 1000 1500 2000 {replace min = `v' if mindesinc_`v' == 1}To be careful, checkegen row = rowtotal(mindesinc*)assert row == 1Nickn.j.cox@durham.ac.ukMartin Weiss *reconstruct Ekaterina`s data clear* input id mindesinc_500_999 mindesinc_1000_1499 mindesinc_1500_1999 101 1 0 0 0 102 0 1 0 0 103 0 0 1 0 104 0 0 1 0 105 0 1 0 0 end *construct the minimum desired income g mindesinc=500 if mindesinc_500_999 replace mindesinc=1000 if mindesinc_1000_1499 replace mindesinc=1500 if mindesinc_1500_1999 l Ekaterina HertogI am dealing with a dataset from a private company and so my data oftencomes in rather strange format and I now came against the followingproblem:I have a set of individuals who answered questions about desired income.It looks as follows: Individ nmb | Min desired income 500 - 999 | 1000 - 1499 | 1500 - 2000 |101 | 0| 0 | 1 |102 | 0| 1 | 1 |103 | 0| 0 | 1 |104 | 1| 1 | 1 |105 | 0| 1 | 1 |Is there a way to automatically recode these binary minimum desiredincome variables into a numerical variable which would state the minimumacceptable figure for each individual?That is some routine which would check "Min desired income 500 - 999"and if it equals 1 then would input 500 for the individual in questioninto a newly constructed variable "Minimum acceptable income" and moveon to the next person and if it equals 0 would look at the value of"1000 - 1499" variable and if it equals 1 would input 1000 for thatperson and move on to the next person and if it is 0 would look at "1500- 2000" variable? * * 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/
