In mvdalab: Multivariate Data Analysis Laboratory

Generates a Graph of the X-residuals

Description

Generates a graph of the X-residuals for both mvdareg and mvdapca objects.

Usage

Xresids(object, ncomp = object$ncomp, conf = c(.95, .99),
        normalized = TRUE, verbose = FALSE)

Arguments

object	an object of class mvdareg or mvdapca.
ncomp	the number of components to include in the calculation of the X-residuals.
conf	the confidence level(s) to use for upper control limit.
normalized	should residuals be normalized
verbose	output results as a data frame

Details

Xresids is used to generates a graph of the X-residuals for both PLS and PCA models.

Value

The output of Xresids is a graph of X-residuals and a data frame listing the X-residuals values.
