I am attempting to do a difference in independent means t-test. I am using international large-scale assessment data and thus need to use the pv command:
pv, pv(low_bench*) jkzone(jk_zone) jkrep(jk_rep) weight(total_student_weight ) jrr timss: reg @pv [aw=@w]
estimates store low_lang_sa06
I then repeat this for another year and save the estimate as low_lang_sa16.
I would like to know how to 1) conduct a difference in independent means test in Stata (between years) from these saved estimates or/& 2) how to use the standard error of each estimate to conduct a t test (if possible). If these questions don't make sense, I would appreciate an explanation.
