Estimation of the proportion of overweight individuals in small areas - a robust extension of the Fay-Herriot model

Publication Abstract

Xie, D.W., Trivellore Raghunathan, and James M. Lepkowski. 2007. "Estimation of the proportion of overweight individuals in small areas - a robust extension of the Fay-Herriot model." Statistics in Medicine, 26(13): 2699-2715.

Hierarchical model Such as Fay-Herriot (FH) model is often used in small area estimation. The method might perform well overall but is vulnerable to outliers. We propose a robust extension of the FH model by assuming the area random effects follow a t distribution with an unknown degrees-of-freedom parameter. The inferences are constructed using a Bayesian framework. Monte Carlo Markov Chain (MCMC) such as Gibbs sampling and Metropolis-Hastings acceptance and rejection algorithms are used to obtain the joint posterior distribution of model parameters. The procedure is used to estimate the county-level proportion of overweight individuals from the 2003 public-use Behavioral Risk Factor Surveillance System (BRFSS) data. We also discuss two approaches for identifying outliers in the context of this application.
