An Alternating Least Squares Method for the Weighted Approximation of a Symmetric Matrix.
ten Berge, Jos M. F.; Kiers, Henk A. L.
Psychometrika, v58 n1 p115-18 Mar 1993
R. A. Bailey and J. C. Gower explored approximating a symmetric matrix "B" by another, "C," in the least squares sense when the squared discrepancies for diagonal elements receive specific nonunit weights. A solution is proposed where "C" is constrained to be positive semidefinite and of a fixed rank. (SLD)
