Class "kcca"

The "kcca" class

Objects from the Class

Objects can be created by calls of the form new("kcca", ...). or by the calling the kcca function.

Slots

kcor:

Object of class "vector" describing the correlations

xcoef:

Object of class "matrix" estimated coefficients for the x variables

ycoef:

Object of class "matrix" estimated coefficients for the y variables

%% \item{\code{xvar}:}{Object of class \code{"matrix"} holds the %% canonical variates for \code{x}} %% \item{\code{yvar}:}{Object of class \code{"matrix"} holds the %% canonical variates for \code{y}}

Methods

kcor

signature(object = "kcca"): returns the correlations

xcoef

signature(object = "kcca"): returns the estimated coefficients for the x variables

ycoef

signature(object = "kcca"): returns the estimated coefficients for the y variables

%% \item{xvar}{\code{signature(object = "kcca")}: returns the canonical %% variates for \code{x}} %% \item{yvar}{\code{signature(object = "kcca")}: returns the canonical %% variates for \code{y}}
