A Bivariate Model to Predict Library Circulation.

Barr, Aiala; Sichel, Herbert S.

Journal of the American Society for Information Science, v42 n8 p546-53 Sep 1991

Discussion of models for library circulation data highlights a new statistical prediction model that creates a flexible regression curve. Linear graphs that result from previous models are discussed, bivariate discrete distributions are explained, and graphs that show library circulation for one year at a time are presented.
