A diagnostic plot for assessing model fit in count data models

Einbeck, Jochen; Wilson, Paul

Abstract

Whilst many numeric methods, such as AIC and deviance, exist for assessing model fit, diagrammatic methods are few. We present here a diagnostic plot, to which we refer as `Christmas tree plot' due its characteristic shape, that may be used to visually assess the suitability of a given count data model.
