A general model for prediction and association is described for the situation in which both criterion and predictor(s) are discrete variables. The approach can be employed for the general case involving any number of predictors, and the related measures of multiple and partial association are described. (Author/GK)

Applying basic decision theory on a neuropsychiatric hospital population indicates that researchers using a prediction schedule will be unlikely to predict a future suicide beyond a 20 percent level of efficiency. Eliminating false negatives was more practical than eliminating false positives in increasing the efficiency of a predictive schedule.…

Describes characteristics of experimental predictor battery of tests developed to supplement the Armed Forces Vocational Aptitude Battery for making selection and classification decisions for entry-level enlisted personnel. Explains procedures used to develop new test battery. Basic psychometric properties of each measure, as determine by large…

Attempted to replicate study which proved predictive validity of premarital inventory PREPARE. Conducted longitudinal study with couples (N=179) who took PREPARE. Found PREPARE predicted with about 80 percent accuracy couples who got divorced from those that were happily married. Claims premarital counseling could potentially help high-risk…

Empirical studies addressing admission to and graduation from a doctoral program focusing on educational leadership are noticeably absent within the professional literature, and this study seeks to fill partially this void through testing specific hypotheses. Archival data were used to conduct a three group discriminant analyses where the…

Earlier studies have suggested that higher education institutions could harness the predictive power of Learning Management System (LMS) data to develop reporting tools that identify at-risk students and allow for more timely pedagogical interventions. This paper confirms and extends this proposition by providing data from an international…

A new approach to partialling components is used. Like conventional partialling, this approach orthogonalizes variables by partitioning the scores or observations. Unlike conventional partialling, it yields a common component and two unique components. (Author/GDC)

New tests for comparing the strength of association between a variable and each of two potential predictor variables are proposed and compared to an existing test in a simulation study. Recommendations for use are made. (Author/JKS)

Authors discovered significant correlations between couse ratings and variables representing commitment and course-end attitudes toward the course; conclusions suggested steps an instructor might take to improve his ratings.'' (Authors)

Assessed the relative predictive validity of obvious (O), neutral (N), and subtle (S) items of the MMPI MA scale for 86 males. Subtle-obvious ratings were compared to criteria in questionnaire, life-history, and objective tests. Correlations among the criteria were generally insignificant, suggesting that hypomania is not a homogeneous construct.…

To be able to conclude anything firm about either a predictor or a criterion from the correlation between the two, a whole range of conditions must be met. Those conditions, which are in effect predictors of validity, are discussed, with the emphasis on the educational situation. (Author)

Compares four closed-formula estimators (Burkett, Claudy, Rozeboom, Browne) and the omit-one method for estimating TRS, the true shrunken correlation (not to be confused with TR, the true multiple correlation). Recommendations are based on artificial populations with known TRS. (Author/SV)
