- Library Book Circulation and the Beta-Binomial Distribution. Gelman, E. Sichel, H. S. Library Circulation Library Statistics Mathematical Models Operations Research Prediction Regression (Statistics) Statistical Analysis Argues that library book circulation is a binomial rather than a Poisson process, and that individual book popularities are continuous beta distributions. Three examples demonstrate the superiority of beta over negative binomial distribution, and it is suggested that a bivariate-binomial process would be helpful in predicting future book circulations.
