| 摘 要： | 用Apriori算法生成的关联规则包含有无用规则，甚至误导规则。为了使生成的规则更有效，引入了统计学中的卡方检验从统计意义上检验规则是否关联，并找到卡方检验值与相关系数的数量关系，实现了两种方法的统一，并用基于相关系数的算法去生成关联规则。

| Abstract: | Association rules generated by Apriori algorithm includes some useless and even misleading rules. To gain more effective rules, a statistical criteria, Chi-Squared was used to measure the associations, furthermore the quantitative relations between the Chi-Squred test and correlation coefficient was found out, and two measures was united to generate association n.des with correlation coefficient. |

| Keywords: | association rules correlation chi-squared test correlation coefficient |
