CFA2级教材323页第六行,关于F test的:the critical value of the F statistic is smaller than 1.87,but larger than 1.79.The value of the test statistic is 1.53.So we clearly cannot reject the null hypothesis that all of the coefficients jointly are equal to 0.即因为F统计量在两个关键值之间,所以我们不能拒绝相关系数为零的假设。我想因为F统计量在两者之间,应该拒绝为零的假设吧?作者: dandman 时间: 2013-8-18 13:17
