问题如下:
6. For the analysis run by Batten, which of the following is an incorrect conclusion from the regression output?
选项:
A.The estimated intercept coefficient from Batten’s regression is statistically significant at the 0.05 level.
B.In the month after the CPIENG declines, Stellar’s common stock is expected to exhibit a positive return.
C.Viewed in combination, the slope and intercept coefficients from Batten’s regression are not statistically significant at the 0.05 level.
解释:
C is correct.
C is the correct response, because it is a false statement. The slope and intercept are both statistically significant.
请解释一下b选项,题目说“in the month after the CPIENG declines” 所以指的是在自变量下降的后一年return的变化,由于这一年是decline,所以return是positive,考虑到均值复归,下一年应该是negative,为什么不能这样理解?
