Naming convention of replicate weight variable names slightly changes throughout the 2014 SIPP Panel.  For Wave 1, the replicate weight variable names are REPWGT1-REPWGT240.  However, for Waves 2+, the replicate weight variable names are REPWT1-REPWT240, and the longitudinal replicate weight variables names are REPWGT1-REPWGT240.  Note the replicate weight and longitudinal replicate weight are in separate data files for each wave in the 2014 SIPP Panel, so the naming convention of the replicate weight variables is unlikely to affect how data users manipulate the data (e.g., merging SIPP data with replicate weight data).
