st: Re: data management - loop?
...
There's a much easier way -- without creating the 250 dummies or any looping:
bysort household var: gen count=_N
bysort household (count): gen byte dummy=count==count[_N]
In the event of ties (two values of var with equal frequency), then both values
will be included by the dummy.

Subject: st: data management - loop?
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?
