Dear Steven, the panel is unbalanced, the sampling unit is thehousehold. The survey is carried on biannually. To each householdis attributed a probability weight each year...but weights aremodified each year in order to take into consideration changes insome known characteristics of the population.thanks a lot Steven Samuels wrote:What are your panels? Do they all have three years of data?Please describe the population sampling process. How did thesampling produce different weights between years?-Steve On Oct 14, 2008, at 12:21 PM, mdeidda@stern.nyu.edu wrote:Dear allI am estimating a 3 year panel (random effect) using surveydata. To get correct estimates I should use sampling weights,but the command xtreg, re does not allow me to use weights...Ican use xtreg with the option mle, which allow me to useanalytic weights. But stata requires weights to be constantwithin panels.Is it correct to use the weights of the last year, and assumethey are constant within panel?Or should I simply ignore weights?
