weights and design variables query Waves 2-5
I was wondering if you could answer a question I have about weights and psu/strata variables for analysing Understanding Society data.
If I want to analyse data from the BPHS, GPS, and EMB samples from Wave 2-5, which comes from both the self-completion questionnaire and the main survey, should I use:
e_indscus_lw: Longitudinal adult self-completion questionnaire weight
e_strata: Sampling strata
e_psu: Primary sampling unit
Many thanks for your time.

There is almost unlimited number of sets of weights we could provide. Yet providing w2+ longitudinal sc weights can be confusing for users. You can use w1 in your analysis as e_indscus_lw includes it. By dropping BHPS you loose a very small sample size, so your analysis results should not be affected.
Again your aim should not be to use a particular sample. Your aim should be to represent a population - and this can be perfectly achieved with e_indscus_lw weights.
Hope this helps, Olena
