A Graphical Tool For Assessing The Suitabilty Of A Count Regression Model

نویسندگان

چکیده

Whilst many numeric methods, such as AIC and deviance, exist for assessing or comparing model fit, diagrammatic methods are few. We present here a diagnostic plot, which we refer to `Quantile Band plot', that may be used visually assess the suitability of given count data model. In case diagnosed inadequacy, plot has unique feature conveying precise information on character violation, hence pointing analyst towards potentially better choice.

A Flexible Regression Model for Count Data

Poisson regression is a popular tool for modeling count data and is applied in a vast array of applications from the social to the physical sciences and beyond. Real data, however, are often overor under-dispersed and, thus, not conducive to Poisson regression. We propose a regression model based on the Conway–Maxwell-Poisson (COM-Poisson) distribution to address this problem. The COM-Poisson r...
