acprob: Robust principal component analysis

Description

Robust principal component analysis / Analyse en composantes principales robuste

Usage

acprob(x,h,center=TRUE,reduce=TRUE,kernel="gaussien")

Value

An object of class acp The object is a list with components:sdevthe standard deviations of the principal components.loadingsthe matrix of variable loadings (i.e., a matrix whose columns contain the eigenvectors). This is of class "loadings": see loadings for its print method.scoresif scores = TRUE, the scores of the supplied data on the principal components.eigEigen values

Details

acpgen compute robust pca. i.e. spectral analysis of a robust variance instead of usual variance. Robust variance: see varrob
