Examines the credibility of inferences based on cross-group comparisons of regression coefficients using Black-White differences in the educational attainment process as an example. Shows that reanalyses of data from previous studies fail to produce consistent results even when major differences in samples, models, and methods are held constant.…

Explored the independent and joint effects of organizational commitment and job satisfaction on variables relevant to employees' withdrawal intentions. Participants (N=175) completed instruments relating to organizational commitment, job-facet satisfaction, and intention to quit. Results indicate commitment bears a strong relationship to…

Research on automated scoring is extended by comparing alternative automated systems for scoring a computer simulation of physicians' patient management skills. A regression-based system is more highly correlated with experts' evaluations than a system that uses complex rules to map performances into score levels, but both approaches are feasible.…

Estimates perceived rates of return to higher education in Cyprus, and uses them in logistic regression analysis to study effect of economic considerations on secondary students' decision to pursue higher education. The mean rate of return to higher education estimated by college candidates is considerably higher than that perceived by labor…

The use of nonparametric quartile regression in examining the impacts of social programs on the distributions of noncategorical outcome measures is demonstrated through the study of earnings effects and income effects in four evaluations of training and employment programs for welfare recipients. Distributional impact estimates yield estimates…

Compares segmentation modeling and logistic regression with regard to a longitudinal study of graduation rates at Ohio State University Agricultural Technical Institute. Suggests that segmentation modeling is as effective as the regression techniques in terms of predictive ability, but that segmentation modeling offers a distinct advantage in…

Examines the cost effectiveness of New Jersey's tuition reimbursement plan for 10-month private school programs for handicapped students, using multiple regression techniques. The study found accounting inconsistencies correctable by organizing an actual cost model that requires pricing of program needs, system cost projections, and a site-based…

A model based on latent trait theory, with maximum likelihood parameter estimates and associated asymptotic tests, is presented. Latent curve analysis is a method for representing development and is an alternative to repeated measures analysis of variance and first-order auto-regressive models. (SLD)

Surveyed 1,773 Massachusetts adolescents to explore relationships among the following topics: (1) alcohol and drug use; (2) perceived susceptibility to human immunodeficiency virus (HIV); (3) use of condoms; (4) effectiveness of condoms in preventing infection; (5) barriers to condom use; and (6) behavioral cues about AIDS related to condom use.…

Offers an improvement over the least-square method that is particularly applicable to fitting the Beer-Lambert equation. Provides typical data and the corresponding graphs. Lists six references. (YP)

A modification index is presented to aid in reformulating hypothetical models rejected after analysis of empirical data. This index is an improvement over the one in the LISREL V computer program in that it takes into account changes in all parameters of the model when one parameter is freed. (SLD)

Presents a series of data sets and answers that can be used to do an inhouse evaluation of common procedures in statistical software programs that are designed for use on microcomputers. Highlights include procedures for t-test, analysis of variance, regression, correlation, and categorical data analysis. (14 references) (LRW)

Describes study that was conducted to investigate the relationship between locus of control and user attitude toward computer based information systems (CBIS) used at work. The impact of user involvement is examined, the hypotheses tested are described, and implications for introducing CBIS into organizations are discussed. (14 references) (LRW)

Evaluates the association of age, self-rated health, and walking activity with 4 measures of cognitive functioning in 6,979 randomly selected people ranging in age from 18 to 94. Assessments included a face-to-face interview regarding health and health beliefs as well as cognitive testing. Analyses indicated that faster reaction time speed was…

Nonoffending mothers' (n=99) self-reported symptom distress was measured across 3 groups of sexual abuse types: incest, relative, and nonrelative. A multiple regression analysis of psychosocial characteristics indicated that a mother's perceived aloneness in facing the crisis and a personal history of adult sexual assault were positively related…
