Stata Percentiles

[Leon Edelman]

set obs 1000
set seed 1
generate x = runiform()

Say I have variable 'x' which is uniform distribution variable and I wish to create Variable X where the values of 'x' are converted into a categorical variable and I specify the percentiles and theyre values where

'X' value in the percentile 0--28.9999 -> 'x' value of 1
'X' value in the percentile 29--31.9999 -> 'x' value of 2
'X' value in the percentile 32--97.999 -> 'x' value of 3
'X' value in the percentile 98--100 -> 'x' value of 4

_pctile x, percentiles(29 32 98)
return list

gen wanted = 1 if x < r(r1)
replace wanted = 2 if x >= r(r1) & x < r(r2)
replace wanted = 3 if x >= r(r2) & x < r(r3)
replace wanted = 4 if x > r(r3)
