Set correlation is explored as an option in analysis of two-way contingency tables. It includes measures of strength of association, significance tests and estimation, power analysis, and computer programs. (SLD)

Criticizes the application of the statistical procedures of the population-genetic approach within evolutionary biology to the study of psychological development. Argues that the application of the statistical methods of population genetics--primarily the analysis of variance--to the causes of psychological development is bound to result in a…

Argues that a truly developmental behavior genetics will have to go beyond the traditional quantitative approach of population genetics in order to produce developmental explanatory content about differences and similarities in developmental outcomes. (MDM)

In multivariate analysis of variance studies with small numbers of subjects (15 or less) per treatment level, probability values reported by the commercial statistical packages SAS and SPSS are conservative for F approximations based on Pillai's trace and liberal for F approximations based on the Hotelling-Lawley trace. Discusses results in terms…

Benefits and limitations of structural equation models for multivariate experiments with incomplete data are presented. Examples from studies of latent variable path models of cognitive performance illustrate analyses with latent variables, omitted variables, randomly missing data, and nonrandomly missing data. (SLD)

Compares family role dysfunction, college adjustment, chemical dependence, and family functioning among college students (n=245) from three groups: dysfunctional homes with significant substance abuse; dysfunctional homes without significant substance abuse; and nonabusing, nondysfunctional homes. Results suggest that substance abuse or dependence…

Comments on some methodological limitations of the research base of "The Bell Curve": blind use of the normal distribution (bell curve); avoidance of nonnormal statistical distributions, which are more appropriate for some social and economic characteristics; copious use of percentiles and quintiles, inappropriate with nonnormal…

Analytical solutions for point and variance estimators of the mediated effect, the ratio of mediated to direct effect, and the proportion of the total effect mediated were determined through simulation for different samples. The sample sizes needed for accuracy and stability are discussed with implications for mediated effects estimates. (SLD)

Attitudes toward rape were examined by assessing the reactions of 95 male and female college students to scenarios about couples in varying degrees of acquaintanceship. Males had more rape-supportive beliefs. It appears that college students view date rape as an extension of traditional male-female sexual interaction. (DM)

Across conditions, differences between population parameters defined by common factor analysis and component analysis are demonstrated. Implications for data analytic and theoretical issues related to choice of analytic model are discussed. Results suggest that principal components analysis should not be used to obtain parameters reflecting latent…

It is argued that the relative scoring method used to score the Ways of Coping Checklist introduces an artifact that confounds multivariate analyses and ignores the individual's general reactivity to the problem. Multivariate analysis is shown to suggest an intricate structural relationship between components of coping and depression. (SLD)

Investigated whether there is a significant difference in the rate of gain in test scores between students who use an integrated learning system (ILS) and students who do not. Nine dependent variables from the Indiana Statewide Testing for Educational Progress examination for third grade students provided the data. (Contains 23 references.)…

The use of scales on the Personality Assessment Inventory (PAI) to detect defensiveness in criminal and nonclinical samples was evaluated with 45 male inmates and 38 male undergraduates under standard conditions or under instructions to feign a positive role. Results indicate that the PAI is susceptible to defensive dissimulation. (SLD)

Effects of repeated administration of cocaine to animals behaving under operant contingencies have depended on when the drug is given. Moderate doses given presession have generally led to a decrease in the drug's effect, an outcome usually referred to as tolerance. When these same doses have been given after sessions, the usual result has been no…

The analysis of discrete dyadic sequential behavior and, in particular, the problem of forecasting future behavior from current and past behavior in such data is the main theme of the present article. We propose to use multivariate multinomial logit models and the potential of which will be demonstrated with data on Imagery play therapy. In such a…
