3.7 Weights

Survey weights were added with data version v6-0-0. There are three types of survey weights for the TwinLife data: Design, Nonresponse, and Panel weights. While design weights address unequal sampling probabilities due to the sampling design, nonresponse weights account for selective response pattern in F2F1. Panel weights for the waves from CATI 1 and onwards account for selective panel attrition. Detailed documentation of the survey weights will be published as a separate technical report in 2022.
