The effectiveness of a national counseling program for Australian Vietnam veterans was evaluated by comparing the symptom levels of 146 clients with those of 546 matched nonclient controls. Multivariate analyses show that the positive effects of the counseling are most apparent in areas of alcohol dependence and dyadic adjustment. (SLD)

Application of multivariate qualitative response models, such as logit regression models, to analysis of risks of all-terrain vehicles is discussed. Data are from national exposure and injury surveys and records of fatalities of the Consumer Product Safety Commission. Suggestions are made for further applications of the method. (SLD)

Describes study of undergraduates that examined uses and effects of learner control of the context or theme of practice examples on a computer-based statistics lesson in combination with the number of examples examined. Student attitudes are discussed, and correlations between learner characteristics and task outcomes are examined. (38 references)…

Studies perceptions of causal attributions pertinent to success and failure in two social class groups from Belgium, West Germany, India, South Korea, and England. Found high agreement among the two social classes as well as among four of the nations, but Indians rated all causes as more external, variable, and uncontrollable. (FMW)

A retrospective cohort design is used to estimate the effect of urinary incontinence (UI) on the public costs of home care services to elderly individuals. Multivariate analyses controlling for other individual, household, and supply characteristics demonstrate that those with UI generate significantly greater public costs for home care services.…

Discussion of expert systems and computerized adaptive tests describes two versions of EXSPRT, a new approach that combines uncertain inference in expert systems with sequential probability ratio test (SPRT) stopping rules. Results of two studies comparing EXSPRT to adaptive mastery testing based on item response theory and SPRT approaches are…

A study used a multivariate approach to assessing college departmental excellence. Factor analysis identified three potentially useful factor clusters ("faculty research,""input," and "student") and seven indicators based on those clusters. Indicators combining faculty research and input and combining all three clusters were found to be the best…

A statistical technique is presented for developing performance standards based on benchmark groups. The benchmark groups are selected using a multivariate technique that relies on a squared Euclidean distance method. For each observation unit (a school district in the example), a unique comparison group is selected. (SLD)

Applies chaos theory to complex social organization, beginning with a mathematical definition of chaos. Shows how a nonlinear equation might be used to describe organization. The conclusion section identifies three approaches to analyzing chaos in social organization: metaphorical analysis, mathematical modeling, and data collection. (36…

This paper provides a method for analyzing data consisting of event sequences and covariate observations associated with Markov chains. The objective is to use the covariate data to explain differences between individuals in the transition probability matrices characterizing their sequential data. (TJH)

Issues the author has explored in his work on the philosophy of statistics are reviewed. Indeterminacy, the place of empiricism, questions of causation and causality, and explorations of language have preceded the study of objectivity. The relationship between objectivity and multivariate statistics is examined. (SLD)

A study involving 109 female adolescents with serious emotional disturbances (ages 9-18) found the following risk factors for early pregnancy: being African American, low family income, dropping out of school, conduct disorder, and substance use disorder. However, according to multivariate analysis, only dropping out of school was a significant…

The approximate degrees of freedom Welch-James (WJ) and Brown-Forsythe (BF) procedures for testing within-subjects effects in multivariate groups by trials repeated measures designs were investigated under departures from covariance homogeneity and normality. Empirical Type I error and power rates were obtained for least-squares estimators and…

Variation in the parts of ASL signs (i.e., phonological variation) has been explained largely by reference to the influence of the preceding and the following segments. This article examines three linguistic variables in ASL: the sign deaf; the location of a class of signs represented by the verb know; and signs produced with a 1 handshape. For…

The aim of this study was to conduct a multivariate assessment of college student drinking motivations at a campus with conventional alcohol control policies and enforcement practices, including the establishment and dissemination of alcohol policies and the use of warnings to arouse fear of sanctions. Two explanatory models were compared:…
