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…

In 1996-1997, within the framework of the European Observatory for Population Education and Information, a comparative survey was conducted among students in final classes of secondary education in several European countries. On the one hand, the survey attempted to assess the effects of education on population in terms of knowledge acquired; the…

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…

Choosing the most appropriate method to handle missing data during analyses is one of the most challenging decisions confronting researchers. Often, missing values are just ignored rather than replaced with a reliable imputation method. Six methods of data imputation were used to replace missing data from two data sets of varying sizes; this…

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:…

The present study aimed to determine which anxiety symptoms in children are associated with teacher awareness and whether teacher awareness differs according to student age and gender. The Multidimensional Anxiety Scale for Children (MASC) was completed by 453 second through fifth grade students and teachers nominated the three most anxious…

This article explores how labor market trends and current employment assistance policies affect reemployment opportunities and emotional well-being in a sample of female dislocated apparel workers. The study follows the displaced women from the time the plant closed for 6 months to assess their financial and emotional well-being as they reentered…
