A method based on the Poisson approximation to the binomial distribution and on the relation between the Chi-Squared distribution and the Poisson distribution is suggested for selected use in determining the number of items and passing scores in mastery Lests. (Author/RL)

Theoretical predictions, based on the confluence model, were made for data from six national surveys of intellectual performance, each relating intellectual performance scores to family configuration variables. The confluence model was capable of accurate prediction in all cases when three parameters were estimated. (Author/RD)

The use of analysis of covariance in conjunction with the multivariate approach to analyzing repeated measures designs is considered for designs involving between- and within-subject factors, one dependent variable, and one observation per subject on the covariate. (Author/RL)

A statistical model for relating latent variables from manifest variables, called a linear structural equation model, is presented. The approach is illustrated by a test theory model and longitudianl study of intelligence. (Author/JKS)

By algebraically defining a school finance structure as a total budget system, partial derivatives can be used to find the kinds of rewards, incentives, and distributions the structure defines for individual districts and among districts. Equity concerns can also be answered. (Author/IRT)

In order to offer an analysis of alternative tax limitation possibilities, the ways in which Leviathan (the nonbenevolent despot model of government) can be constrained by elements of the "fiscal constitution" are examined. Journal availability: see EA 511 898. (Author/IRT)

Concludes that public school enrollments are not very sensitive to public school spending, so that it seems unlikely that a major cutback in public school spending will trigger the hypothesized unraveling of the public schools. Journal availability: see EA 511 898. (Author/IRT)

Dunnett's procedure for comparing K-1 treatments with a control is discussed within the context of three nonparametric models: those of Kruskal-Wallis, Friedman, and Cochran. (Author/MH)

A short account is given of the Coxeter Symposium on geometry. Included are brief descriptions of selected sessions and a description of a touchable geometry display. (MK)

The matching law for reinforced behavior solves a differential equation relating infinitesimal changes in behavior to infinitesimal changes in reinforcement. The equation expresses plausible conceptions of behavior and reinforcement, yields a simple nonlinear operator model for acquisition, and suggests a alternative to the economic law of…

Two techniques for interpretation of fitted log-linear models in contingency table analysis are discussed. The use of odds ratios as opposed to direct interpretation of the fitted model is argued for. (Author/JKS)

A theory and a procedure are presented for estimating a domain parameter and item parameters for test items in a homogeneous domain, such that the combined domain and item parameters account for observed proportions right for each item in a test. (CTM)

A brief overview is presented of the use of soap bubbles to solve minimal problems. A new class of problems that can be solved with soap film models is presented. (MP)

A multivariate model was constructed to test and compare sets of social location and consciousness factors explaining political behavior among two random samples of college and noncollege youth. The form of Mannheim's generation unit model provided a useful tool for comparing youth groups within the same generation; the contents await replication…

Investigates the problem of assigning faculty to courses at a university. A program is developed that is both efficient, in that integer programming is not required, and effective, in that it facilitates interaction by administration in determining the optimal solution. The results of some empirical tests are also reported. (Author)
