supplementalProjection {ExPosition} | R Documentation |
Performs a supplementary projection across ExPosition (and related) techniques.
supplementalProjection(sup.transform = NULL, f.scores = NULL, Dv = NULL,
scale.factor = NULL, symmetric = TRUE)
sup.transform |
Data already transformed for supplementary projection. That is, the output from: |
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). |
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.
