看了下DOC最近的报告,纠正一下,ITC和DOC在决定采用计算倾销价格方法时,采用的是“Cohen’s d test”,即“a generally recognized statistical measure of the extent of the difference between the mean of a test group and the mean of a comparison group”,即先分析相关性,然后再进行“ratio test assessment“。这是DOC决定采纳“the average-to-average (‘A-A’) method”,还是"the average-to-transaction ('A-T') method"(alternative method)的基础,即“the Department tests whether using an alternative method, based on the results of the Cohen’s d and ratio tests described above, yields a meaningful difference in the weightedaverage dumping margin as compared to that resulting from the use of the A-A method only”。本人上述理解是否正确,请楼主确认。因此,这里要解释的是Cohen‘s d Test,坐等高人。
