Description

Performs a supplementary projection across ExPosition (and related) techniques.

Usage

1
2
supplementalProjection(sup.transform = NULL, f.scores = NULL, Dv = NULL, 
scale.factor = NULL, symmetric = TRUE)

Arguments

sup.transform

Data already transformed for supplementary projection. That is, the output from: caSupplementalElementsPreProcessing, mdsSupplementalElementsPreProcessing, pcaSupplementaryColsPreProcessing, or pcaSupplementaryRowsPreProcessing.

f.scores

Active factor scores, e.g., res$ExPosition.Data$fi

Dv

Active singular values, e.g., res$ExPosition.Data$pdq$Dv

scale.factor

allows for a scaling factor of supplementary projections. Primarily used for MCA supplemental projections to a correction (e.g., Benzecri).

symmetric

a boolean. Default is TRUE. If FALSE, factor scores are computed with asymmetric properties (for rows only).

Value

A list with:

f.out

Supplementary factor scores.

d.out

Supplementary square distances.

r.out

Supplementary cosines.

It is preferred for users to compute supplemental projections via supplementaryRows and supplementaryCols. These handle some of the nuances and subtleties due to the different methods.
