Scalar Measures of Fit for Poisson GLMs Models

Description

Calculates scalar measures of fit for models with count dependent variables along the lines described in Long (1997) and Long and Freese (2005).

Usage

poisfit(obj)

Arguments

obj

A model of class glm with family=poisson.

Details

poisfit calculates scalar measures of fit (many of which are pseudo-R-squared measures) to describe how well a model fits data with a count dependent variable.

Value

A named vector of scalar measures of fit
