B.correlation between precteanactuvalues of the pennt variable is 0.36. C.correlation between precteanactuvalues of the pennt variable is 0.60. C is correct.The multiple R-squarefor the regression is 0.36; thus, the mol explains 36 percent of the variation in the pennt variable. The correlation between the precteanactuvalues of the pennt variable is the square root of the R-squareor 0.36=0.60\sqrt{0.36}= 0.600.36=0.60. rt
NO.PZ201512020300000304 我印象里面只有在单因子回归里面,把R-square开方才能得到correlation 多因子也是一样的?还是我把其他知识点混淆了?
NO.PZ201512020300000304 老师能不能用中文翻译一下correlation这个词
了解R^2中X和Y的关系 但是不太明白Mutiple R中x和y的关系 所以不太明白为什么C正确 请老师讲解一下 谢谢
如何修正A?
