2014 SIPP Panel Wave 4: Problems with WPFINWGT

January 16, 2020

In Wave 4 of the 2014 SIPP, an inconsistency was identified with the value of WPFINWGT. For some person-month records, WPFINWGT has missing values. In previous waves in the 2014 SIPP Panel, zero-weight person-month records received a weight value of zero rather than missing. This error affects 1,349 person-month records. Data users should replace these missing values for WPFINWGT with zero.
