Generating Variable in Stata? -


i have categorical variable , trying calculate new variable multiplies each response frequency. ex:

      total |        freq.      ------------+---------------           1 |          6                   2 |          12                   3 |          9                   5 |          5                   6 |          10

i have variable presents sum n each response (i.e. 1=6, 2=24, 3=27, etc.). tried few calculations using egen, did not seem work. please let me know if has insight.

i think example should show general tactic:

sysuse auto, clear  bysort rep78: egen count_rep78 = count(rep78) gen freq_x_val = rep78*count_rep78  browse rep78 count_rep78 freq_x_val

in example rep78 categorical variable.

essentially, create count variable category's frequency in bysort step. multiply new count variable categorical variable , you're done.
