问题如下：
How does the correlation between pairs of explanatory variables affect the interpretation of the coefficients in a regression with multiple explanatory variables?
选项：
解释：
Regression coefficients are interpreted as holding all other variables constant, and so the correlation between the regressors is immaterial to the interpretation of the coefficients.
老师好，之前在说assumption的时候有提到，所有的x应该互为iid。这样的话correlation 应该等于= 0.correlation对于 slope coefficient 没有影响。请问可以从这个角度切入吗？

Regression coefficients are interpreteholng all other variables constant, anso the correlation between the regressors is immaterito the interpretation of the coefficients.这句话翻译成中文如何理解？
