Inverse Gaussian model for small area estimation via Gibbs sampling
Fassil Nebebe, Cynthia M DeSouza, Yogendra P Chaubey
Abstract
We present a Bayesian method for estimating small area parameters under an inverse Gaussian model. The method is extended to estimate small area parameters for finite populations. The Gibbs sampler is proposed as a mechanism for implementing the Bayesian paradigm. We illustrate the method by application to household income survey data, comparing it against the usual lognormal model for positively skewed data.
