图书馆图书订购的两种预测模型性能比较

The Performance Comparison of Two Prediction Models for Library's Books Ordering

基于重庆医科大学图书馆的中文图书流通数据与订购数据,用相对残差平方和预测效益对图书馆图书流通与订购数据进行比较分析,并分析了两种预测模型的性能,指出正比模型比线性模型有更为优越的性能。

Based on Chinese books＇ circulation data and ordering data of the library of Chongqing Medical University, this paper makes comparative analysis on books＇ circulation data and ordering data of the library by using the relative SSR （square sun of residuals） and the prediction efficiency, and points out that the performance of the proportional model is better than that of the linear model.
