Details Report in Correspondence Analysis

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

Equation shown here

where:

P is the matrix of counts divided by the total frequency

r and c are row and column sums of P

the D matrices are diagonal matrices of the values of r and c

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:
