Description

This function computes the autocorrelation function estimates for a selected parameter.

Usage

acfplot(object, parm = NULL)

Arguments

object

an object of class mvdareg, i.e., plsFit.

parm

a chosen predictor variable; if NULL a random predictor variable is chosen

Details

This function computes the autocorrelation function estimates for a selected parameter, via acf, and generates a graph that allows the analyst to assess the need for an autocorrelation adjustment in the smc.
