plot.lmp: Diagnostic plots for a lmp object

In normalp: Routines for Exponential Power Distribution

Description

This function produces four plots: a plot of residuals against fitted value, a Normal Q-Q plot, an Exponential Power Distribution Q-Q plot, a Scale-Location plot, with a p-root of the standardized residuals against the fitted values.

Usage

## S3 method for class 'lmp'
plot(x, ...)

Arguments

x	A lmp object, typically result of lmp.
...	Further arguments passed to or from other methods.

Details

The standardized residuals in the Normal Q-Q plot are those of an object lm; in the Exponential Power distribution Q-Q plot and in the scale location plot the standardized residuals are computed as (residuals-mp)/sp.
