R: Plots The Fitted Values of a GAMLSS Model

fittedPlot {gamlss} | R Documentation

## Plots The Fitted Values of a GAMLSS Model

### Description

This function, applicable only to a models with a single explanatory variable, plots the fitted values for all the parameters of a GAMLSS model against the (one) explanatory variable. It is also useful for comparing the fits for more than one model.

### Usage

    fittedPlot(object, ..., x = NULL, color = TRUE, line.type = FALSE, xlab = NULL)

### Arguments

`object` | a fitted GAMLSS model object(with only one explanatory variable)
`...` | optionally more fitted GAMLSS model objects
`x` | The unique explanatory variable
`color` | whether the fitted lines plots are shown in colour, `color=TRUE` (the default) or not `color=FALSE`
`line.type` | whether the line type should be different or not. The default is `color=FALSE`
`xlab` | the x-label

### Value

A plot of the fitted values against the explanatory variable
