eigenvectors.fwdmv {Rfwdmv}R Documentation

Retrieve an Eigenvector of the Covariance Matrix Estimate from an fwdmv Object

Description

An accessor method to retrieve an eigenvector of the covariance matrix estimate from an fwdmv object.

Usage

eigenvectors.fwdmv(x, which.vector = 1)

Arguments

x an fwdmv object.
which.vector an integer specifying which eigenvector should be returned.

Value

a list with one element for each group in the fwdmv object x. Each element is a matrix where row i contains the components of the which.vector eigenvector of the covariance matrix estimate computed during step i of the forward search.
