Statistical Details for Correspondence Analysis

This section contains details for correspondence analysis in the Contingency platform.

Lists values from the following singular value decomposition (SVD):

where:

P is the matrix of counts divided by the total frequency

r and c are row and column sums of P

Dr and Dc are diagonal matrices of the values of r and c, respectively

Λ is the column vector of the singular values reported in the details report

For more information about singular value decomposition, see “The Singular Value Decomposition” in Multivariate Methods.

The row coordinates (rc) and column coordinates (cc) in the Details report are computed as follows:
