Webinar Abstract
A data-driven area-specific selection procedure of the area effects in the nested error model is proposed through a mixture model. Two different specifications of the mixture model are considered. An expectation-maximization (E-M) method is designed for fitting each proposed mixture model. Under the proposed mixture models, two alternative new predictors of general small area indicators are proposed. A parametric bootstrap method is used to estimate the mean squared errors of the proposed predictors. The properties of the new predictors and of the bootstrap procedure are analyzed in simulation experiments.
This is joint work with A. Bikauskaite and D. Morales
