问题如下:
The results reported in Exhibit are most accurately
interpreted as indicating that:
选项:
A.
multicollinearity is not present.
B.
the reported R2 is spurious.
C.
the regression coefficients have inflated standard
errors.
解释:
The pairwise correlation is low. The only case in
which correlation between independent variables may be a reasonable indicator
of multicollinearity occurs in a regression with exactly two independent
variables, as is the case in this problem. Furthermore, the additional classic
symptoms of multicollinearity (high R2and significant F-statistic
but not significant coefficients) are not present.
请用中文说一下判断标准。
