As a sequel to my previous reply, here is one technique
illustrated:
. forval i = 1/5 {
2. qui count if rep78 == `i'
3. local counts "`counts' `r(N)'"
4. }
. di "`counts'
2 8 30 18 11
. chitesti `counts'
One advantage of this technique is that
will work fine when observed frequencies
are 0. You just have to use -forvalues-
or -foreach- to cycle over the possible
values of a variable relevant to your
test.
This could also be automated in a program.
