Generalized Eigenvalue Problems with Positive Semi-Definite Matrices.
Peer reviewed Peer reviewed
de Leeuw, Jan – Psychometrika, 1982
Recent work (EJ 208 813) showing that generalized eigenvalue problems in which both matrices are singular can be solved by reducing them to similar problems of smaller order is discussed. Possible extensions of the work are indicated. (Author/JKS)

Some Extensions of the Full Rank Multivariate Linear Model.
Carlson, James E.; Timm, Neil H. – 1980
This paper presents two extensions of the full-rank multivariate linear model that are particularly useful in multivariate analysis of covariance (MANCOVA) and repeated measurements designs. After a review of the basic full-rank model, an extension is described which allows restrictions of a more general nature. This model is useful in the…
