SPcaGrid-class function

Class SPcaGrid - Sparse Robust PCA using PP - GRID search Algorithm

Holds the results of an approximation of the PP-estimators for sparse and robust PCA using the grid search algorithm in the plane. 1.1

class

Objects from the Class

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

Extends

Class "PcaGrid-class", directly. Class "PcaRobust-class", by class "PcaGrid-class", distance 2. Class "Pca-class", by class "PcaGrid-class", distance 3.

Methods

• getQuan: signature(obj = "SPcaGrid"): ...
