Some Empirical Results with Guttman's Stronger Lower Bound for the Number of Common Factors
Peer reviewed Peer reviewed
Kaiser, Henry F.; Hunka, Steve – Educational and Psychological Measurement, 1973
Authors conclude that, in the world of real data sample correlation matrices, Guttman's stronger lower bound is not of practical use in determining the effective number of common factors. (Authors/CB)

A Note on Allocating Items to Subtests in Multiple Matrix Sampling and Approximating Standard Errors of Estimate with the Jackknife
Peer reviewed Peer reviewed
Shoemaker, David M. – Journal of Educational Measurement, 1973
Investigated empirically through post mortem item-examinee samplings were the relative merits of two alternative procedures for allocating items to subtests in multiple matrix sampling and the feasibility of using the jackknife in approximating standard errors of estimate. (Editor)

A Reliability Coefficient For Maximum Likelihood Factor Analysis
Peer reviewed Peer reviewed
Tucker, Ledyard R.; Lewis, Charles – Psychometrika, 1973
Maximum likelihood factor analysis provides an effective method for estimation of factor matrices and a useful test statistic in the likelihood ratio for rejection of overly simple factor models. A reliability coefficient is proposed for analysis of factor solution. (Author/RK)

Development of the Armed Services Vocational Aptitude Battery: Forms 8, 9, and 10. Final Report 19 December 1975-31 January 1977.
Fruchter, Dorothy A.; Ree, Malcolm James – 1977
In order to meet the needs of all the Armed Services, new forms of the Armed Services Vocational Aptitude Battery (ASVAB) must periodically be developed, refined, and standardized on an appropriate normative sample. Since one of the uses of the ASVAB is to determine candidate suitability for military service, it is necessary for the…

Using an Induced Course Load Matrix.
PDF pending restoration PDF pending restoration
Sanford, Timothy R. – 1977
An induced course load matrix (ICLM) can be a valuable tool for examining the educational process at most postsecondary educational institutions, but the complexity and bulk of the ICLM computer printout is a hindrance. Experiences in using an ICLM at the University of North Carolina at Chapel Hill are described. Examples from an ICLM printout are…
