Hello all,
Hopefully I have solved this, but wanted to see if this made sense:
I asked:

after I :
svytab dummy cat4, row format(%12.3f) se
I can then
test _b[p11]=_b[p21]
test _b[p12]=_b[p22]
.....etc
Is this test valid (variance-wise) for a test that two proportions
from the same survey are different, given the use of svytab?
