LDA: normalization of eigenvectors (see SPSS)
...)
it says, that the matrix with the eigenvectors
V
usually are not normalized to the length of 1, but in the way that the
following holds (SPSS does the same thing):
t(Vstar)%*%Derror%*%Vstar = I
where Vstar are the normalized eigenvectors. Derror is an "error" or
"within" squaresum- and crossproduct matrix (squaresum of the p
variables on the diagonale, and the non-diagonal elements are the sum of
the crossproducts). For Derror the following holds: Dtotal = Dtreat +
Derror.
Since I assume that many of you are familiar with this transformation:
can anybody of you tell me, how...
