Description

Hi, I want to make sure I am using the BHPS longitudinal weights correctly in my analysis. I am analysing respondents to the self-completion interview in 4 waves of data: BHPS waves N, O, & R, and USOC Wave B, using both random effects models (using xtmixed in Stata) and fixed effects models (using xtreg, fe). My analyses are restricted to English 18+ respondents only.

As there is no BHPS longitudinal self-completion weight, I have been using the BHPS 2001 longitudinal main interview weight (b_indin01_lw) as the best substitute. For example:

xtset pid
xtreg y x1 x2 [pweight=b_indin01_lw], fe

Am I OK with this, or would another approach give me less biased estimates?

Best,
Rob
