R: Global Deviance of a GAMLSS model

deviance.gamlss {gamlss} | R Documentation

## Global Deviance of a GAMLSS model

### Description

Returns the global, -2*log(likelihood), or the penalized, -2*log(likelihood)+ penalties, deviance of a fitted GAMLSS model object.

### Usage

    ## S3 method for class 'gamlss'
    deviance(object,  what = c("G", "P"), ...)

### Arguments

`object` | a GAMLSS fitted model
`what` | put "G" for Global or "P" for Penalized deviance
`...` | for extra arguments

### Details

`deviance` is a generic function which can be used to extract deviances for fitted models. `deviance.gamlss` is the method for a GAMLSS object.

### Value

The value of the global or the penalized deviance extracted from a GAMLSS object.
