For a sample of seven and eight-year old Nigerian elementary pupils, validity coefficients of a modified matrix completion instrument entitled Modified Hall's Matrices, were determined relative to two achievement tests. The coefficients were quite high. (Author/JKS)

Empirical Bayes methods are shown to provide a practical alternative to standard least squares methods in fitting high dimensional models to sparse data. An example concerning prediction bias in educational testing is presented as an illustration. (Author)

Employed were a small sample of fifth graders to examine techniques for assessing the validity of psychosocial maturity (PSM) and the scales used to measure it. Three validation techniques were examined: (1) Data obtained from self-report scales, teacher ratings, and peer ratings were used to generate three multitrait-multimethod matrices (total…

Development of an alternate form of Raven's Standard Progressive Matrices Test is described. Reliability analysis with 449 children of differing racial/ethnic backgrounds showed good reliability and comparable predictive validity. The alternate form is a promising research tool. (SLD)

A general linear model (GLM), using least-squares techniques, was used to develop a criterion measure to replace freshman year grade point average (GPA) in college admission predictive validity studies. Problems with the use of GPA include those associated with the combination of grades from different courses and disciplines into a single measure,…

A procedure for predicting categorical outcomes using categorical predictor variables was described by Moonan. This paper describes a related technique which uses prior probabilities, updated by joint likelihoods, as classification criteria. The procedure differs from Moonan's in that the outcome having the greatest posterior probability is…
