Weights for repeated cross sectional study
50%
Description
Hi,
I am working on Understanding Society as a repeated cross-sectional study looking only for participants between 16-30 years old in each wave with the purpose of conducting group based trajectory modelling; participants have to appear at least in two time points. From the support #1739 it seems I can use cross-sectional weights, but I just wanted to make sure this is the right approach or are there any other recommended practices?
Thank you.
Best wishes,
Martina

Martina,
Thank you. If you use information within people longitudinally (e.g. you compare between time points) you would need longitudinal weights.

Hope this helps,

Hi Olena,
Thank you for your reply.
However, since the data is repeated cross-sectional, per each wave not every participant will appear longitudinally that is why the focus is not on individual changes but population changes over time; this is what is creating confusion over whether I should use cross-sectional or longitudinal. I hope you can definitely confirm the required weights.
Many thanks

Martina,
If you are using each wave cross-sectionally, why do you require for participants to have answers in at least 2 waves?
