So you want the ratio of means and se, but that seems to be exactly what
-ratio- gives you:
*************
webuse highschool, clear
svyset
svy: ratio height/weight
quietly svy: mean height weight
nlcom (myratio: _b[height]/_b[weight])
*************

Betreff: st: ratio function
dear Sir/Madam
How to come around command like this?
svy: mean(columnA)/mean(columnB)
I would like to estimate ratio of means and its standard error. How is
it possible with STATA?
It is strange that function "ratio" takes into account just pairs....but
why when "ratio" divides whole mean(columnA)/mean(columnB)? Why the
function ignores missing values? In real life is very improbable that I
have perfect paired variables.
thank you
Roman Kasal
