Dear Stata users,

in my panel dataset I want a dummy for the most occurred value in a variable.

e.g.  for a household a variable can take values from 1 to 250, value 15 is the most named
value in one household, so I want a dummy which is 1 when the household named 15
otherwise 0.

I have some idea but I'm lost in getting the proper loop:


tab var, gen(var)

 		forvalues i=1(1)250 {

 			bysort household: gen N_`i'=sum(var`i')
 			bysort household: replace N_`i'=N_`i'[_N]
}

* Now some loop for:

 	bysort hh: gen dummy=1 if N_1 > N_2 & N_1 > N_3  & N_1 > N_4 ********more
possible values from 1 to 250 but not every number is named*************  & var1 ==1

* here all other possibilities...

Some idea or an easier way?

Thanks.

Alex
