Examines relationships among the parameters of the Zipf size-frequency distribution as well as its sampling properties. Highlights include its importance in bibliometrics, tables for the sampling distribution of the maximal value of a finite Zipf distribution, and an approximation formula for confidence intervals. (Author/LRW)

The Generalized Inverse Gaussian-Poisson Distribution is suggested as an all-embracing mathematical model for bibliometric frequency distributions. Twelve examples are given which show that the new model cannot be rejected by virtue of an objective chi-squared test. A mathematical appendix and 20 references are included. (Author/EJS)

Describes research which measured the efficiency of role operators through frequency of appearances in PRECIS input strings for 200 abstracts related to taxation, genetic psychology, and Shakespearian drama. Frequencies of appearance of major categories of role operators, role operators in different subjects, individual main line operators, and…

Psychology studies often have low statistical power. Sample size tables, as given by J. Cohen (1988), may be used to increase power, but they are based on Monte Carlo studies of relatively "tame" mathematical distributions, as compared to psychology data sets. In this study, Monte Carlo methods were used to investigate Type I and Type II…

Probes publishing and citing patterns of Indian space scientists and engineers, highlighting productivity; sources in which published and from where cited; frequency distributions of publishing in and citing from journals and conference proceedings; frequency distribution of number of references cited and self-citations; comparison of citing and…

Describes methodology for the gathering of useful collection management data and reports results of study which analyzed circulation data and sampled in-library use at a Government Printing Office depository to explore circulation and in-library use frequency distributions, circulation and in-library use, and age of publications used in the…

Introduces two data distortion methods (Frequency-Imposed Distortion, Frequency-Imposed Probability Distortion) and uses a Monte Carlo study to compare their performance with that of other distortion methods (Point Distortion, Probability Distortion). Indications that data generated by these two methods produce accurate statistics and protect…

Survey of Ohio State University faculty members and administrators examines their attitudes and perceptions regarding need for, and potential use of, a computerized database to increase efficiency of graduate school administration, and to collect and generate data for academic departments' use in improving programs. Proposed database design is…
