Collinearity Models in the Eigenvalue Problem
Solution of the eigenvalue problems can be based on inverting matrices built from regularized vectors. The regularization parameters are equal to the eigenvalues of the given matrix after fitting in accordance to the collinearity models. In this approach the eigenvectors are equal to the columns of the inverted matrix.
A new procedure of matrix inversion with the basis exchange algorithm has been recently proposed. In accordance with this procedure the inverse matrix is computed in an iterative manner by gradual replacement of unit vectors by successive regularized vectors. Such replacement is impossible if a new regularized vector depends linearly on the vectors which are already in the basis.
