[MV] mca, p. 414, fourth displayed equation and following text
S = P - cc′
c is called the column mass.
B and S are symmetric.
Thus the singular-value decomposition
commonly associated with CA is equivalent to the spectral or eigen
decomposition of S.
|
S = D(c)-1/2
(P - cc′) D(c)-1/2
c is called the column mass.
D(c) is the diagonal matrix with diagonal c;
D(c)-1/2 is therefore the diagonal matrix with
elements 1/sqrt(ct),
where ct is an element of c.
B and S are symmetric.
Thus the singular-value decomposition
commonly associated with CA is equivalent to the spectral or eigen
decomposition of S.
