I am using weighted data and generating proportions of one variable, over another, e.g, after sorting VAR 2, I write the command prop VAR 1 [pweight=weight], over (VAR 2), generating proportions. I know I can use lincom or test to generate equivalency tests, but the former use a t test and the later an F test (Which generates the same p value as the t test). I understand that when comparing proportions a chi square test should be used, but this option is not available in STATA. While I can find chi square calculators on the web they seem to be more for comparing proportions in two samples rather than comparing whether, e.g. in below _subpop_1 for _prop_1 = _subpop_1 for _prop_3. Any advice would be appreciate, including any known chi square STATA ado file. Much thanks
