Wave 3 equivalent of b_indscbh_xw
I am conducting analysis of a several waves of data spanning BHPS and USoc, using only the BHPS cohort. I am including cases with missing waves and so I am using cross-sectional weights for each wave. For USoc wave 2 I used b_indscbh_xw as the cross-sectional weight for the self-completion form for adults. In USoc wave 3 this variable is not available, and is instead replaced by a combined weight c_indscub_xw. My question is whether this 'combined' weight is suitable for a cross-sectional analysis of only the BHPS cohort, or whether it is intended to be used when analysing the combined BHPS, GPS, EMB samples together?
If it cannot be used to analyse only the BHPS cohort, please could you advise me which weight, if any, is appropriate.
