To modify my earlier suggestion, your code could be gen min = 7000 foreach v of numlist 6000 5000(500)1000 0 { replace min = `v' if mindesinc_`v' == 1 } replace min = 0 if no_desired_income == 1 Nick n.j.cox@durham.ac.uk Ekaterina Hertog The real structure of my data is as I stated originally, rather than as Martin described it: e.g. input id mindesinc_500_999 mindesinc_1000_1499 mindesinc_1500_1999 101 1 1 1 1 102 0 1 1 1 103 0 0 1 1 104 0 0 1 1 105 0 1 1 1 Basically once the person finds a certain income acceptable he or she finds every income above acceptable too and puts 1s, rather than 0s. At the moment I used one of the earlier advices I got with a bit of a modification gen mindesinc=0 replace mindesinc=7000 if desired_income_above_7000==1 replace mindesinc=6000 if desired_income_6000_6999==1 replace mindesinc=5000 if desired_income_5000_5999==1 replace mindesinc=4500 if desired_income_4500_4999==1 replace mindesinc=4000 if desired_income_4000_4499==1 replace mindesinc=3500 if desired_income_3500_3999==1 replace mindesinc=3000 if desired_income_3000_3499==1 replace mindesinc=2500 if desired_income_2500_2999==1 replace mindesinc=2000 if desired_income_2000_2499==1 replace mindesinc=1500 if desired_income_1500_1999==1 replace mindesinc=1000 if desired_income_1000_1499==1 replace mindesinc=0 if desired_income_0_999==1 | no_desired_income==1 I know it is not very elegant, but I thought this would pick up the lowest acceptable income. >> Nick Cox wrote: >>> A variation on the same idea: >>> gen min = 500 >>> foreach v in 1000 1500 2000 { replace min = `v' if mindesinc_`v' >>> == 1 } >>> >>> To be careful, check >>> egen row = rowtotal(mindesinc*) assert row == 1 >>> Nick n.j.cox@durham.ac.uk >>> Ekaterina Hertog >>> I am dealing with a dataset from a private company and so my data >> often >>> comes in rather strange format and I now came against the following >>> problem: >>> >>> 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 desired >>> income variables into a numerical variable which would state the >> minimum >>> acceptable 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 >>> question >> >>> into a newly constructed variable "Minimum acceptable income" and move >> >>> on 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 that >>> person 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/
