Computational Aspects of the Greatest Lower Bound to the Reliability and Constrained Minimum Trace Factor Analysis.
Peer reviewed Peer reviewed
ten Berge, Jos M. F.; And Others – Psychometrika, 1981
Several algorithms for computing the greatest lower bound to reliability or the constrained minimum-trace communality solution in factor analysis have been developed. The convergence properties of these methods are examined. A uniqueness proof for the desired solution is offered. (Author/JKS)

Weighted Minimum Trace Factor Analysis.
Peer reviewed Peer reviewed
Shapiro, Alexander – Psychometrika, 1982
Minimum trace factor analysis has been used to find the greatest lower bound to reliability. This technique, however, fails to be scale free. A solution to the scale problem is proposed through the maximization of the greatest lower bound as the function of weights. (Author/JKS)
