回归分析在测定最佳图书复本量中的应用

本文从调查图书馆图书复本量分布及其读者借阅图书的分布情况出发，应用回归分析方法得出图书复本量与实际拒借率为双曲线回归关系，并以求解该双曲线的最大曲率点坐标，测得最佳图书复本量的值和对应的理想拒借率。

An Application of Regression Analysis to the Determination of Optimal Collection Copy Number

Starting from the investigation of distribution of the number of dublicates of library collection and the number of user needs, a hyperbola regression relationship between the collection copy number and the refused rates has been developed with the help of regression analysis method. Based on the hyperbola, the optimal collection copy number and theoretical refused rates have been determined in the calculation of coordinates of the biggest point of curvature.
