Keywords: CPS; generalized variance functions; longitudinal generalized variance functions; design effects; implementation

Many current surveys such as the Current Population Survey (CPS) follow the same households at regular time intervals so that longitudinal quantities such as transitions in employment status and poverty status could be studied. In this research, we propose longitudinal generalized variance functions (LGVFs) to produce convenient estimates of variances by incorporating time effect into modeling. Asymptotic properties of some certain type of estimators are investigated. Implementation of the methods to CPS shows that LGVFs are efficient in producing the standard error estimates.
