Because multivariate statistics are increasing in popularity with social science researchers, the challenge of detecting multivariate outliers warrants attention. Outliers are defined as cases which, in regression analyses, generally lie more than three standard deviations from Yhat and therefore distort statistics. There are, however, some…

This paper reviews graphical and nongraphical procedures for evaluating multivariate normality by guiding the reader through univariate and bivariate procedures that are necessary, but insufficient, indications of a multivariate normal distribution. A data set using three dependent variables for two groups provided by D. George and P. Mallery…

This paper reviews the concept of experimentwise Type I error. While "testwise" alpha refers to the probability of making a Type I error for a single hypothesis test, "experimentwise" error refers to the probability of having made a Type I error anywhere within the study. Experimentwise error concerns are the basis for two…

Criteria for assessing variable performance in multivariate analysis of variance (MANOVA) are considered, examining criteria suggested by Huberty and Wisenbaker (1992), the contribution to linear discriminant function scores and the contribution to grouping variable effects. It is proposed that the two criteria be amalgamated as the contribution…

Proposes a comprehensive approach, generalized constrained multiple correspondence analysis, for imposing both row and column constraints on multivariate discrete data. Each set of discrete data is decomposed into several submatrices and then multiple correspondence analysis is applied to explore relationships among the decomposed submatrices.…

Average reliability of the coefficient is suggested as a multivariate extension of the classical reliability coefficient. It is shown that this coefficient is identical to the mean redundancy of the observed variables conditional on the true variables. (Author/SLD)

A nonparametric class of intervariable association indeces is presented that follows the logic of point symmetry adjustment of the Pearsonian phi coefficient. This approach is extended to multipoint scales. These indeces may be attractive alternatives to the Pearson correlation coefficient for multivariate analyses. (SLD)

Proposes a method for performing survival analysis with latent variables with dual aims of scoring subjects with respect to a psychological variable of interest and distinguishing the varying extents to which items are capable of measuring the construct. Illustrates this discrete proportional hazards model. (SLD)

Proposes a generalization of Cohen's kappa coefficient (J. Cohen, 1960) to address the problem of accounting for overall chance-corrected interobserver agreement among the multivariate ratings of several judges. The statistic's metric is conventional and in the univariate case it is equivalent to existing extensions of the kappa coefficient to…

This study describes discourse patterns produced by 46 Alzheimer disease (AD) patients and 53 normal elderly subjects in two picture-supported narratives. Nine measures derived from a cognitive model of discourse processing were obtained and submitted to cluster analysis. Results indicate that discourse patterns elicited from both stimuli were…

The paper reports on a study among primary-school students of the process of deriving word meaning from written context in a first language. A sequential analysis of think-aloud protocols revealed that the students inferred one or more meanings, checked their inferences and then rejected or accepted them. These activities were performed in a…

The current study explored differences in financial behaviors between college students in Georgia who retained the merit-based HOPE Scholarship and those who lost it. Logistic regression was used to analyze data from a sample of 557 undergraduate students from a large southeastern university. Students who initially had HOPE Scholarships but lost…

Giving to charities comes in two major forms: time and money. This study explores whether donors/nondonors and volunteers/nonvolunteers can be uncovered in the Taiwanese context using demographic, socio-economic, psychographic, and attitudinal variables suggested by the interdisciplinary literature. Data were collected by a large-scale telephone…

The popularity of distance education has grown rapidly over the last decade in Taiwan's higher education, yet many fundamental teaching-learning issues are still in debate. While teacher-student interaction is a key success factor in distance education, little work has been done on the teachers. The intent of this research was to clarify teacher's…

Purpose: Marketing communication practitioners in higher education have not yet identified specific subgroups with similar characteristics within the prospective student (target) market, and do not always know which preferred sources learners consult when deciding on a tertiary institution for further or higher education. In addition, little is…
