rank-sum test

Based on four tests ( simple t test, wilcoxon rank test, pair wise test, and binomial test), we find that the average correlation coefficient within the family is significantly higher than the correlation coefficient between the family and outside families.

通过两总体均值检验（t检验），Wilcoxon秩和检验，配对检验以及Binomial检验等四种方法，我们发现家族内基金的平均相关系数显著高于家族间基金的平均相关系数。
