supplementalProjection4distatis function

Supplementary element(s) projection in DISTATIS

supplementalProjection4distatis: Computes for distatis

the projection as supplementary element(s) (a.k.a. "out of sample") of a set of squared matrices. The matrices to be projected need to be of the same type (e.g., distance, correlation) as the matrices used inn the original call to distatis.

supplementalProjection4distatis(res.distatis, elsupp)

Arguments

• res.distatis: the results of the function distatis
• elsupp: the supplementary elements (i.e., a 3D array).

Returns

the coordinates of the supplementary and active elements in the RV space. *** HA comment: Maybe we also want to send the square cosines to give the quality of representation.
