Examines the extent to which demographic, academic, and attitudinal factors predict the teaching practice and course performance of British postgraduate students. Finds that commitment to teaching was a strong predictor of job status among students nine months after completing a Postgraduate Certificate of Education course. (KO)

Procedures for implementing parallel analysis (PA) criteria in practice were compared, examining regression equation methods that can be used to estimate random data eigenvalues from known values of the sample size and number of variables. More internally accurate methods for determining PA criteria are presented. (SLD)

Monte Carlo techniques were used to examine regression approaches to external unfolding. The present analysis examined the technique to determine if various characteristics of the points are recovered (such as ideal points). Generally, monotonic analyses resulted in good recovery. (TJH)

Data from a sample of 66 countries were analyzed to investigate 4 hypothesized societal-level correlates of the divorce rate: socioeconomic development, female labor participation, the sex ratio, and dominant religion. Regression analyses revealed that all factors except religion had a significant effect on the crude divorce rate. Theoretical…

Cognitive Differentiation Analysis (CDA) represents a method to measure the correspondence of an individual vector or a composite vector of descriptor ratings to a matrix of pair-wise dissimilarity judgments where both sets of judgments are assumed to be ordinal. The zero intercept regression extension of CDA is described. (TJH)

A simple procedure for establishing convergent and discriminant validity is presented, as an alternative to the LISREL-based nested model used by R. P. Bagozzi (1978) and K. F. Widaman (1985). Ordinary least-squares regression is used, with the correlation between measures as the dependent variable. (SLD)

Focusing on linear interpolation, an accurate method of implementing parallel analysis, this article contains tables of 95th percentile eigenvalues from random data than can be used with sample sizes of 50 to 500 subjects and between 5 and 50 variables. An empirical example illustrates how to obtain the eigenvalues. (SLD)

The use of multiple regression for analyzing data from the regression-discontinuity design (RDD) is examined, considering the effects of random measurement error in the pretest, treatment-effect interactions, and curvilinearity in the regression analysis of RDD. Three sets of conditions of increasing generality are reviewed. (SLD)

Adaptive forms of weighted structural regression are developed and discussed. Bootstrapping studies indicate that the new methods have potential to recover known population regression weights and predict criterion score values routinely better than do ordinary least squares methods. The new methods are scale free and simple to compute. (SLD)

Dimensional measures of aspects of personality disorders (PD) were developed. Convergence of these measures with the "Big Five" personality factors was studied in 300 general population subjects. Results suggest substantial similarity between the five factors and PD measures, though the latter cannot be entirely subsumed by the Big Five…

Studies binomial, negative binomial, and gamma regression models and gives a detailed description of inference procedures based on them. The process of model fitting and evaluation is illustrated by examples referring to the determination of endpoints in acute and chronic toxicity tests. (17 references) (Author/MDH)

Total of 305 adults ranging from 19-84 years of age and 100 college students were given a battery of tests that measured cognitive abilities and memory. Results indicated that a large proportion of age-related variance in cognition and memory was reduced when statistical control procedures, such as hierarchical regression, were used to eliminate…

Uses Michigan school district data and canonical regression analysis to investigate the effects of communities' socioeconomic characteristics in the production of high school education. Although socioeconomic characteristics have significant effects independent of school resources, these effects are difficult to ascertain. Parent educational…

Describes the use of regression analysis in eliminating sex discrimination in a university's salary structure and examines regression models usually accepted by courts. Estimates salary regressions for a large, midwestern university for 1983-84 in a simulating exercise exploring alternative elimination methods. Includes 23 references and 11 court…

Discussion of models for library circulation data highlights a new statistical prediction model that creates a flexible regression curve. Linear graphs that result from previous models are discussed, bivariate discrete distributions are explained, and graphs that show library circulation for one year at a time are presented.
