I meant to say -sort- already does the randomization for you among ties In this case, -sort- and -keep- together are enougth to minimize our objective function but that's because this is a specially simple case Renzo -----Original Message----- From: Renzo Comolli [mailto:renzo.comolli@yale.edu] Sent: Friday, November 28, 2003 9:48 PM To: 'statalist@hsphsun2.harvard.edu' Subject: Re: st: Nearest value Read the help for -egen- it will help How do you plan to handle ties (i.e. a case in which there is more than one household which is at the same minimal distance from the average consumption)? If you plan to pick one of them at random then . egen meanconsumption=mean(consumption) . generate absconsumptiondev=abs(meanconsumption-consumption) . sort absconsumptiondev . keep in 1 -sort- already does the maximization for you among ties If you plan to keep all the ties . egen meanconsumption=mean(consumption) . generate absconsumptiondev=abs(meanconsumption-consumption) . egen mindevfromavgcons=min(absconsumptiondev) . keep if absconsumptiondev==mindevfromavgcons Ciao Renzo ---------------------------------------------------------------------------- ---- *From Ramani Gunatilaka <Ramani.Gunatilaka@buseco.monash.edu.au> To statalist@hsphsun2.harvard.edu Subject st: Nearest value Date Sat, 29 Nov 2003 01:13:43 +0000 Hi everybody, This is probably a very simple question, but I have not been able to figure out a solution. I have a data set with consumption and other variables such as number of adults, district, sector for each household. I need to write a programme that requires selecting the particular household whose consumption is nearest to the mean consumption of all the households. Can someone please tell me, what is the Stata command that will do this for me?
