Abstract:
|
This paper develops an estimator for the bias due to attrition nonresponse weighting within a longitudinal survey, with associated standard errors. The estimator was proposed by Bailey (2004) in connection with the Census Bureau's Survey of Income and Program Participation (SIPP), for cross-sectional survey items. It is generalized here to longitudinal survey items, and design-based variance formulas and estimators based on VPLX and the Fay (1989) method plus some alternative approximations are given. The methods are illustrated and results presented using data from the SIPP 1996 panel. Additionally, the paper explores the use of estimated attrition-weighting for some items in a longitudinal survey like SIPP in a regression setting to provide attrition-weighting for other items.
