A major problem in the research concerning distributional and other properties of reliability coefficients has been the non-existence or inaccessibility of adequate test data for use in empirical verification of hypothetical conclusions. The purpose of this paper is to develop a technique for the simulation of test item scores through the use of…

The objective of this project was to investigate the adequacy of statistical models developed by G. E. P. Box and G. C. Tiao for the analysis of time-series quasi-experiments: (1) The basic model developed by Box and Tiao is applied to actual time-series experiment data from two separate experiments, one in psychology and one in educational…

This publication discusses the difficulties of calculating reliable income estimates for particular groups of people and presents a methodology for overcoming those obstacles. Basically, the procedure involves setting up cumulative distributions of housing values, rental values, and family incomes for each census tract. Average housing values and…

This study was conducted to determine the effects of using various levels of tutorial statistical software for the tentative identification of nonseasonal ARIMA models, a statistical technique proposed by Box and Jenkins for the interpretation of time-series data. The Box-Jenkins approach is an iterative process encompassing several stages of…

A large number of correlational models for cross-tabular analysis are available for utilization by social scientists for data description. Criteria for selection (such as levels of measurement and proportional reduction in error) do not lead to conclusive model choice. Moreover, such criteria may be irrelevant. More pertinent criteria are…

EXPER SIM has been translated into two basic software systems: the Michigan Experimental Simulation Supervisor (MESS) and Louisville Experiment Simulation Supervisor (LESS). MESS and LESS have been programed to facilitate student interaction with the computer for research purposes. The programs contain models for several statistical analyses, and…

An interactive, computerized model developed for Old Dominion University utilizes university historical data, demographic characteristics, projected selected economic variables and population figures by various age groups and planning districts to forecast enrollment, financial projections, and future fiscal conditions of the institution. The…

Describes British Library's work on Systems Dynamics, a set of techniques for building simulation models based on analysis of information feedback loops. Highlights include macro-simulation modelling activities of social science disciplines, systems analyses and models of information retrieval processes and library services, policy models, and…

Using the systematic plan of the Public Education Project developed in Region J of North Carolina as its model, this guide presents in detail seven major steps in organizing a public education project for emergency medical services: (1) assessing needs; (2) survey methodology; (3) determining objectives; (4) media usage--both mass media and…

A method for modeling the structure of large social systems has been developed which is based on the interpersonal communication networks present in the functioning system. Recent developments in techniques and computer software have made possible the analysis of networks of several thousand persons. The new technique provides a method for…

The major purpose of this study is to further the development of procedures which minimize current limitations of creativity instruments, thus yielding a reliable and functional means for assessing creativity. Computerized content analysis and multiple regression are employed to simulate the creativity ratings of trained judges. The computerized…

The 189 papers are organized by topic: simulation methodology, hybrid systems and methodology, simulation in the chemical and physical sciences, simulation in environmental sciences and biological systems, systems for managerial and social sciences, simulation credibility, energy, systems engineering, and government simulation facilities.
