Your request does not make sense. Analytic weights are proportional to the the residual variance of the dependent variable for each observation. Their use minimizes the standard errors of the regression coefficients. Please look at any regression text.

Hi All,
I'm running simple cross-sectional regressions. I would like to know whether it is possible to make Stata apply a different aweight to each separate explanatory variable.
Usually at the end of the regression I can just write [aweight = exp], but this would apply the same aweight to each explanatory variable. I would like to know whether it's possible to specify a different exp as an aweight for each different explanatory variable, and whether that would make any sense or not. My explanatory variables are financial ratios, so I would need a different weight for each different denominator.
Many thanks,
Natacha
