supplementaryRows function

Supplementary rows

Computes factor scores for supplementary observations (rows).

supplementaryRows(SUP.DATA, res)

Arguments

• SUP.DATA: a data matrix of supplementary observations (must have the same measures [columns] as active data)
• res: ExPosition or TExPosition results

Details

This function recognizes the class types of: epPCA, epGPCA, epMDS, epCA, epMCA and TExPosition methods. Further, the function recognizes if Hellinger (as opposed to row profiles; in CA, MCA and DICA) were used.

Returns

A list of values containing:

• fii: factor scores computed for supplemental observations

• dii: squared distances for supplemental observations

• rii: cosines for supplemental observations
