โœฆ Synopsis

We propose a stepwise confirmatory procedure for the detection of multiple outliers in two-way contingency tables. The method begins with perturbation diagnostics to provide a reliable set of candidate outliers, then applies an adding-back iterative algorithm to assess their relative discordancy. Using two real data sets, the proposed procedure is shown to be less susceptible to both masking and swamping problems than residual-based measures.

The decomposition for the complete point symmetry model in a rectangular contingency table is shown. Also the respective decompositions for the local point symmetry model and the reverse local point symmetry model in a square contingency table are given. Moreover teat procedures for the decomposed m
