This description of the technical details required for using the HIER-GRP computer program, which was developed to group or cluster regression equations in an iterative manner so as to minimize the overall loss of predictive efficiency at each iteration, contains a discussion of the basic algorithm, an outline of the essential steps,…

The authors isolate seven patterns of cultural choice using a cluster analysis of a multidimensional scale of items from a 1977 survey of leisure activities in the South. They then use regression analysis to isolate the social demographic correlates of the clusters. (Author/RM)

A comparison was made of responses to two types of personality inventory items, either sentence-type items or adjective-type items. Three methods of analysis were applied. It was concluded that the two item types give approximately equal results. (CTM)

This study was concerned with various schemes for reducing the number of variables in a multivariate analysis. Two sets of illustrative data were used; the numbers of criterion groups were 3 and 5. The proportion of correct classifications was employed as an index of discriminatory power of each subset of variables selected. Of the four procedures…

Most responses to educational and psychological test items may be represented in binary form. However, such dichotomously scored items present special problems when an analysis of correlational interrelationships among the items is attempted. Two general methods of analyzing binary data are proposed by Horst to partial out the effects of…

PRIME is a library of 44 batch-oriented computer routines: 20 major package programs, which use 12 statistical utility routines, and 12 other utility routines for input/output and data manipulation. This manual contains a general description of data preparation and coding, standard control cards, input deck arrangement, standard options, and…

This bibliography contains works that illustrate and apply multivariate statistical methods in the analysis of empirical data in the field of urban and regional planning. The bibliography has been designed for use by planning students and the professional planner. The first section of the bibliography lists some elementary and intermediate level…

A research design, decision support system, and results of a comparative analysis of enrollment and financial strength (of private institutions granting masters and doctoral degrees) are presented. Cluster analysis, discriminant analysis, multiple regression, and an interactive decision support system are used to compare the enrollment and…

Describes a study of high school students that investigated the use of microcomputers to teach principles relating to the design and interpretation of graphs. Results related to student achievement, higher order thinking skills, and behavioral protocols are discussed. A sample assignment sheet and test questions are appended. (66 references) (LRW)

A study was conducted to describe the television viewing habits of grade 6 children in primary schools within the metropolitan area of Melbourne, Australia; to examine the nature of the relationships between factors found to be relevant in explaining television behavior; and to examine the relationship between television behavior and school…

Just as urban ecologists have shown that social behavior such as delinquency is related to spatial patterns, educational achievement should logically be related to socio-spatial patterns. Accordingly, the hypothesis of the present study is that school neighborhoods can be ecologically grouped so as to enhance the prediction of achievement. The…

The effects of college environments on student achievement on three GRE area achievement tests, when the initial ability of students was controlled were studied. A wide variety of environmental measures for 95 colleges were included. The method computed within-school regression lines, then colleges were clustered on regression lines, using a…
