Description

Dear Support Team,

I tsset (pidp wave) the April and May Study. Can I only use the weight (betaindin_xw) cross-sectionally for April and May separately or can betaindin_xw be used for the collapsed (April and May) sample to derive representative descriptions?

Many thanks in advance.

Best wishes,

Darja

Hello Darja,

ca_betaindin_xw = i_indinui_xw * non-response probability based on a model of non-response between main W9 &W1. This weight is non-zero for W9 respondents who also responded in W1

cb_betaindin_xw = i_indinui_xw * non-response probability based on a model of non-response between main W9 &W2. This weight is non-zero for W9 respondents who also responded in W2, but may not have responded to W1.

You will need to include in the sample all those with a wave one weight and use the wave one weight; or include all those with a wave two weight and use the wave two weight.

If you want to focus on respondents who did an interview at both waves one and two then you will need a longitudinal weight. The covid19 team is currently working to produce this weight and the plan is to include it in a future data release.

Information on weights for this survey is also available in the user guide: https://www.understandingsociety.ac.uk/documentation/covid-19/user-guide

Does this answer your question? If not, please let us know.

Best wishes,
Alita
