Overview

For use with SAS Version 9.2 or higher for Windows.

The %WeightedTVEM SAS macro (version 2.6) fits TVEMs on complex datasets that involve clustering (e.g., students are nested within schools) and survey weights (e.g., participants represent different numbers of population members due to systematically unequal probabilities of selection). Before attempting to use %WeightedTVEM, users should familiarize themselves with the %TVEM SAS macro (version 3.1 or higher).
