acfResid {gamlss}

ACF plot of the residuals

Description

This plot display the ACF and PACF of the residuals of a gamlss or other fitted model (provided that they have been standardised appropriately. Is is appropriate for time series data.

Usage

acfResid(obj = NULL, resid = NULL)

Arguments

obj

A gamlss model or other fitted model where the resid() function applies exist

resid

if obj does not exist the argument here will be used

Details

The ACF and PACF for the residuals r, squared residuals r^2, r^3 and r^4 are plotted

Value

The relevant plots are displayed
