单项选择题
Of the following explanations, which is least likely to be a valid explanation for divergence between statistical significance and economic significance（）
A. Transactions costs.
B. Data errors.
C. Taxes.
答案
参考答案：B
解析：
While data errors would certainly come to bear on the analysis, in their presence we would not be able to assert either statistical or economic significance. In other words, data errors are not a valid explanation. The others are all mitigating factors that can cause statistically significant results to be less than economically significant.
