Using longitudinal weights for data in long format

Hello,

our analysis uses PATH data waves 1-4 with appropriate longitudinal weights. Upon reading the manual, it was my understanding that the VARPSU and VARSTRAT were used for computing the weights and should not be used as cluster and stratification variables in the analyses and repweights should be used instead (as they include the information about stratification and clustering). However, when using data in long format (for mixed model with timepoints nested within ID), it is unclear to me how to account for this nesting (within ID) using repweights? Would the weights still be applicable?

Thank you
