The distribution of the likelihood ratio test for testing the reality of the covariance matrix of a complete multivariate normal distribution is investigated. (Author/RC)

Demonstrates the value of spreadsheets for teaching sociology using Lotus 1 2 3 as an example. Shows how a Cholesky factorization, an eigenstructure solution, a correlation analysis, and a discriminant analysis may be performed using a spreadsheet or a BASIC program (included). (BSR)

A factor replication procedure (FACTOREP) was evaluated using four psychometrically equivalent synthetic correlation matrices containing an imposed three-subscale structure. Comparisons of the structure revealed by two, three, four, and nine-factor rotations using the FACTOREP showed that only the three factor solutions were replicable across all…

A generalized congruence maximization procedure for the case of m matrices is presented. The orthogonal rotation procedure simultaneously maximizes the sums of all coefficients of congruence between corresponding factors of m factor matrices. (NSF)

Two methods for solving matrix equations are discussed. Both operate entirely on a matrix level. (MNS)

This paper explores levels of perceived parental influence on mathematics learning among over 700 students in China and Australia. Students in China had stronger perceived parental influences than students in Australia, and while students in China, Chinese speaking students in Australia, and other language speaking students in Australia…

A matrix of characteristics associated with transformational leadership and with high reliability organizations was developed. Using the matrix as a lens, researchers examined a successful school involved in a school improvement effort to understand the success more fully. Transformational leaders provide opportunities for personal growth for…

Seven value-type catergories which can be used in guiding a programing situation analysis are social-psychological, economic, physiological and health, socio-political, education, environment and natural resources, and ecological relationships. These categories are related to seven basic questions in a matrix model to determine program needs. (MS)

Young children were given tasks in which they were to identify small variations in complex patterns. Results indicated the children were able to perform the task more accurately than developmental models would have predicted. (ST)

This article examines the utility of multi-matrix sampling as a technique in health education research that permits collection of large quantities of data without lengthy questionnaires or excessive time demands on respondents. Advantages and limitations of multi-matrix sampling are delineated through a hypothetical example. (Authors/CJ)

Describes how Suffern (New York) High School creates its master class schedule using a computer-generated "conflict matrix" that shows the enrollment for each course and the number of students who would experience scheduling conflicts if any two courses were offered at the same time. (Author/RW)

A commentary is made on a previously published article concerning testing the equivalence of covariance matrices. An error in the previous article (by the same authors) is pointed out and the consequences of the error are discussed. (JKS)

Examined the role played by experience with multidimensional stimuli in the child's ability to separate variables. (Author/DB)
