| Abstract: | The influence of the reader loans behavior is firstly selected to determine the literature purchasing duplicates.Based on the correlation relation between the library loans rate and the mean duplicates of 20 categories books,the method of linear regression analysis is used to predict its mean duplicates in the coming 2008-2009 school year.The prediction result plays a key role in determining all duplicates that will be purchased.As the representative in the library of colleges and universities,the H languag... |
