Sensitivity Analysis for Fixed Effects in the Hierarchical Model: A Gibbs Sampling Approach.
Seltzer, Michael H.
Journal of Educational Statistics, v18 n3 p207-35 Fall 1993
A Bayesian approach to sensitivity of inferences to possible outliers involves recalculating marginal posterior distributions of parameters of interest under assumptions of heavy tails. This strategy is implemented in the hierarchical model setting through Gibbs sampling, a Monte Carlo technique, and illustrated through a reanalysis of data on children's vocabulary growth. (SLD)
