Title: A Study of the Composite Estimator for Change Rate

Abstract:

Most panel surveys are performed repeatedly, so that the overlapped respondents could provide better estimates of the monthly/yearly change. But, as the repeated interviews with the same panel increase the burden, rotation sample design is used. Recent studies suggest AK-composite estimator for the level change, Y_(t)-Y_(t-1), in rotated panel survey, which was first introduced by Kumar and Lee (1983). In this study, we introduce a composite estimator for estimating the change rate, {Y_(t)-Y_(t-1)}/Y_{t-1}, not the change itself. We compare MSEs of composite estimators and those of simple estimator with In-for-6 simulated data.
