Advantages of the use of multivariate commonality analysis are discussed and a small data set is used to illustrate the analysis and as a model to enable readers to conduct such an analysis. A noteworthy advantage of commonality analysis is that commonality honors the relationships among variables by determining the degree to which predictors in a…

This study was undertaken to provide a comparison of primary/elementary teachers' perceptions in Australia and the United States of the skills, competencies, and behavioral attributes that principals should possess to administer an effective school. Utilizing the Audit of Principal Effectiveness, 140 primary teachers in Australia and 347…

The mixed model analysis of variance assumes a mathematical property known as sphericity. Several preliminary tests have been proposed to detect departures from the sphericity assumption. The logic of the preliminary testing procedure is to conduct the mixed model analysis of variance if the preliminary test suggests that the sphericity assumption…

A growing controversy surrounds the strict interpretation of statistical significance tests in social research. Statistical significance tests fail in particular to provide estimates for the stability of research results. Methods that do provide such estimates are known as invariance or cross-validation procedures. Invariance analysis is largely…

Interest in the health care needs and medical care use patterns of older persons has steadily increased in recent years. The major goals of this study were to describe the variability of health services use by older persons and examine the extent to which specific factors moderate the relationship between life stress exposure and subsequent use of…

Traditionally the unit of analysis in marital research has been the individual spouse. More recently the marital relationship has often been defined as a process of interaction and dynamic exchanges such that spouses have autonomous needs as well as corporate needs for interdependence. Thus modern systems theory heightens the importance of both…

The Wechsler Intelligence Scale for Children - Revised (WISC-R) and the Wechsler Intelligence Scale for Children (WISC) were administered in counter-balanced order to 81 children aged 7-12 in New South Wales, Australia. Canonical correlation analysis showed the total redundancy values of WISC-R given WISC and WISC given WISC-R to be .58 and .61…

Based on the assumption that a relationship exists between public county-based child welfare agencies in Pennsylvania and their environments, this study draws clues as to the nature of this relationship from (1) a review of the literature, and (2) a multivariate analysis of agency service delivery measures and social and demographic variables.…

A partial least squares method is described for estimating parameters of linear structural relation models. This method is an extension of Herman Wold's proposal for estimation parameters without distributional assumptions, using some algorithms worked out by Paul Horst. The method (LISPLS) determines a different number of latent variables from…

Canonical-redundancy analyses were computed across the Profile of Mood States and the Eight State Questionnaire on a sample of 289 college undergraduates in order to estimate the degree of measurement overlap of the two multidimensional mood-state instruments. (Author/BS)

Comments on Kerwin et al.'s article on covariance structure analysis (LISREL). Cautions that much effort must be made in developing the theory that describes the relationships among constructs and in establishing the measurement of these constructs before covariance structure is used. (ABB)

Seven data sets (namely, clinical data on children) were subjected to clustering by seven algorithms--the B-coefficient, Linear Typal Analysis; elementary linkage analysis, Numerical Taxonomy System, Statistical Analysis System hierarchical clustering method, Taxonomy, and Bolz's Type Analysis. The little-known B-coefficient method compared…

Private preschool and Head Start teachers' interactive behaviors with children of middle and lower socioeconomic status and with boys and girls were compared. Statistical analyses indicated that teachers of lower SES children had fewer verbal communications with children and more interactions with other adults. (Author/JAZ)

Five experiments were performed to determine whether different amounts of attention were demanded of readers under the following conditions: (1) during the reading of relevant segments of text prefaced by questions; (2) by questions following relevant segments of text; and (3) during the reading of prefatory questions.

Since computer programs have been available for estimating and testing linear causal models, these models have been used increasingly in the behavioral sciences. This paper discusses the problem that very different causal structures may fit the same set of data equally well. (Author/LMO)
