This memorandum is the manual for the VARAN (VARiance ANalysis) program, which is the latest addition to a series of computer programs for multivariate analysis of variance. As with earlier programs, analysis of variance, univariate and multivariate, is the main target of the program. Correlation analysis of all types is available with printout in…

Faced with a nonstandard, complicated practical problem in statistical inference, the applied statistician sometimes must use asymptotic approximations in order to compute standard errors and confidence intervals and to test hypotheses. This usually requires that he derive formulas for one or more asymptotic sampling variances (and covariances)…

Appendix A is concerned with the characteristics of the user communities and of the information service centers as important factors in the representation of an information service system. The basic characteristics of both centers and communities include their number, size, geographic distribution, and scope of interest. These characteristics are…

A general Computer program is described that will compute asymptotic standard errors and carry out significance tests for an endless variety of (standard and) nonstandard large-sample statistical problems, without requiring the statistician to derive asymptotic standard error formulas. The program assumes that the observations have a multinormal…

Four major discussions are presented related to economic issues involved with property rights as applied to computer software and data bases. The first discussion qualitatively compares the relative incentives to computer software producers found in alternative regimes of copyright and trade secrecy. The latter is found to have certain…

A computer program for solving the conditional likelihood equations arising in the Rasch model for questionnaires is described. The estimation method and the computational problems involved are described in a previous research report by Andersen, but a summary of those results are given in two sections of this paper. A working example is also…

The components of an information system for institutions in higher education are described. The information produced from such a system will be that which is required not only for record keeping and operations but also for planning and budgeting. Technical details are not included, only an overview of the main components of the system as seen from…

General documentation for the Enrollment Projection Model used by the Maryland Council for Higher Education (MCHE) is provided. The manual is directed toward both the potential users of the model as well as others interested in enrollment projections. The first four chapters offer administrators or planners insight into the derivation of the…

The Design of Training Systems (DOTS) project was initiated by the Department of Defense (DOD) to develop tools for the effective management of military training organizations. Phase 2 involved the design and development of three computer-based mathematical models, described in detail in this report. The models described are the System…

Progress on the development of a mathematical model and associated computer programs for use by the Illinois State Library in evaluation and planning of the interlibrary loan (ILL) network is summarized. Pertinent published literature on ILL networks is reviewed in terms of network structure, operations, satisfaction of requests, and costs. A flow…

The Design of Training Systems (DOTS) project was initiated by the Department of Defense to develop tools for the effective management of military training organizations. Phase 2 of the project, from which this report emanates, involved the design and development of three computer-based mathematical models and their validation. Volume 1 presents…
