PcaNA-class: Class "PcaNA" Principal Components for incomplete data

In rrcovNA: Scalable Robust Estimators with High Breakdown Point for Incomplete Data

Class "PcaNA" Principal Components for incomplete data

Description

Contains the results of the computations of classical and robust principal components for incomplete data using an EM algorithm as descibed by Serneels and Verdonck (2008)

Objects from the Class

Objects can be created by calls of the form new("PcaNA", ...) but the usual way of creating PcaNA objects is a call to the function PcaNA which serves as a constructor.

Slots

call, center, scale, loadings, eigenvalues, scores, k, sd, od, cutoff.sd, cutoff.od, flag, n.obs:

from the "Pca-class" class.

Ximp:

the data matrix with imputed missing values

Extends

Class "Pca-class", directly.

Methods

getQuan

signature(obj = "PcaNA"): ...
