This is quite easy by using the result variables, following summarize.
Notice the option ", d": If you forget the percentiles will not be available
E.g. for a variable AGE:
summ AGE ,d
..... output cut out .....
75% 48 74
..... output cut out .....
* You can also see the result variables by:
return list
scalars:
..... output cut out .....
r(p50) = 41
r(p75) = 48
..... output cut out .....
* to create your indicators:
gen high = (AGE >= r(p75) )
gen low = ( AGE < r(p25) )
list h AGE
high AGE
1. 0 47
2. 1 49
..... output cut out .....
