基于K.Pearson卡方假设检验模型的馆藏结构合理性判别

Judgment of Collection Structure Based on K.Pearson Chi-square Hypothesis Test Model

高校图书馆的主要职能是为教学和科研服务,所以馆藏建设要针对本校的学科建设情况进行,并在各个学科之间保持一定的平衡。本文采用数理统计学中的K.Pearson卡方假设检验模型对高校馆的馆藏结构和学科建设的一致性进行判断,通过这种定量的方法来判别图书馆馆藏在各个学科之间是否保持平衡,为将来的馆藏建设提供指引。

The main function of the university library is for teaching and research services,so books purchased must meet the need of the disciplines and maintain certain balance among them.This paper tests the consistency of the collection and the disciplines,by using the K.Pearson chi-square hypothesis test model to find if there is imbalance among the collection corresponding to the disciplines and guide the future of the book procurement.
