Many stata functions do not work with probability weights, or svy commands, but will work with frequency weights. Can I converty pweights to fweights? What do I lose if I just specificy the pweights as fweights? Only standard errors being too small, or will point estimates be off also?

I’m intersted in income for the population as a whole over time and for specific subpopulations defined by education, occupation, race and sex. I’m worried that the flat file may be too small and would like to use the full weighted file, but probability weights are not allowed for many functions in stata (they will take frequency weights).

Kernel desnity plots

Mean

Standard Deviation

Cofficient of Variation (SD / M)

And Percentiles
