问题如下:
4. Based on Exhibit 1, the predicted ROE for DF Associates is closest to:
选项: A. 10.957%.
选项:
10.957%.
16.593%.
20.388%.
解释:
C is correct. The regression equation is as follows:
beginarraylY∧i=9.442+0.069X1i+0.681X2iROE=9.442+0.069(ESG)+0.681(Tenure)=9.442+0.069(55)+0.681(10.5)=9.442+3.795+7.151=20.388begin{array}{l}{\overset\wedge Y}_i=9.442+0.069X_{1i}+0.681X_{2i}\\ROE=9.442+0.069(ESG)+0.681(Tenure)\\=9.442+0.069(55)+0.681(10.5)\\=9.442+3.795+7.151=20.388beginarraylY∧i=9.442+0.069X1i+0.681X2iROE=9.442+0.069(ESG)+0.681(Tenure)=9.442+0.069(55)+0.681(10.5)=9.442+3.795+7.151=20.388
请问怎么知道X1是55;X2是10.5?
题目中的DF是什么意思?
已明白。

如果某一项的系数不significant的话,还需要算它吗?
