Dear Stata Users,
I have two related questions:
1) Im trying to calcuate mortality ratios for
different sub-populations using survey data.
Is it very naive from my side to use the following
commands?
svyset AI06 [pw= expweigh], strata( AI05)
svy: ratio death, over (Province)
I also get similar results with prop.
2) I dont get any SE because I have strata with one
sampling unit. I see that Stata suggests (as also some
books) to delete or collapse the strata with one
sampling unit. Do you know what are the implications
for this? Would I need to collapse the strata
according to region?
thanks,
Gaby
