What are your panels? Do they all have three years of data? Please
describe the population sampling process. How did the sampling
produce different weights between years?

Dear all
I am estimating a 3 year panel (random effect) using survey data.
To get correct estimates I should use sampling weights, but the
command xtreg, re does not allow me to use weights...I can use
xtreg with the option mle, which allow me to use analytic weights.
But stata requires weights to be constant within panels.
Is it correct to use the weights of the last year, and assume they
are constant within panel?
Or should I simply ignore weights?
I really appreciate your help,
Manuela
