Minimim Rank and Minimum Trace of Covariance Matrices.

Riccia, Giacomo Della; Shapiro, Alexander

Psychometrika, v47 n4 p443-48 Dec 1982

Some mathematical aspects of minimum trace factor analysis (MTFA) are discussed. The uniqueness of an optimal point of MTFA is proved, and necessary and sufficient conditions for any particular point to be optimal are given. The connection between MTFA and classical minimum rank factor analysis is discussed. (Author/JKS)
