\title{Canonical correlation analysis}
\description{
\code{canocor} performs canonical correlation analysis on the
basis of the standardized variables and stores extensive output
in a list object.
}
\usage{
canocor(X, Y)
}
\arguments{
\item{X}{ a matrix containing the X variables }
\item{Y}{ a matrix containing the Y variables }
}
\details{
\code{canocor} computes the solution by a singular value
decomposition of the transformed between set correlation matrix.
}
\value{
Returns a list with the following results
\item{ccor }{ the canonical correlations }
\item{A }{ canonical weights of the x variables }
\item{B }{ canonical weights of the y variables }
\item{U }{ canonical x variates }
\item{V }{ canonical y variates }
\item{Fs }{ biplot markers for x variables (standard coordinates) }
\item{Gs }{ biplot markers for y variables (standard coordinates) }
\item{Fp }{ biplot markers for x variables (principal coordinates) }
\item{Gp }{ biplot markers for y variables (principal coordinates) }
\item{fitRxy }{ goodness of fit of the between-set correlation matrix }
\item{fitXs }{ adequacy coefficients of x variables }
\item{fitXp }{ redundancy coefficients of x variables }
\item{fitYs }{ adequacy coefficients of y variables }
\item{fitYp }{ redundancy coefficients of y variables}
}
