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

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

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?
Thanks,
Ramani
