i think that it is correct to use
gen wt=sqrt(pop)
regress y x1 x2 x3 [aweigth=wt]

My
dependent variable is the mortality rate. Since the variance of
ln(d/p)
is inversely proportional to p (population), this implies
heteroskedasticity. To correct for it, observations should be weighted
by the square root of the denominator of the mortality rate, i.e.,
population. In Stata, i am using
xi: regress y x1 x2 i.country i.year [w=1/pop],
Is that correct? I might also use the robust option
I would appreciate any answers
