diffdic: Differences in penalized deviance

Description

Compare two models by the difference of two dic objects.

Usage

dic1 - dic2
diffdic(dic1, dic2)

Value

An object of class ``diffdic''. This is a numeric vector with an element for each observed stochastic node in the model.

The diffdic class has its own print method, which will display the sum of the differences, and its sample standard deviation.

Arguments

dic1, dic2

Objects inheriting from class ``dic''

Author

Martyn Plummer

Details

A diffdic object represents the difference in penalized deviance between two models. A negative value indicates that dic1 is preferred and vice versa.
