| Feb 23, 2015 at 23:23 | comment | added | gung - Reinstate Monica | @whuber, do you think Positive correlation and negative regressor coefficient sign, Positive correlation but negative coefficient in regression, Is the model wrong if a coefficient changes from minus in correlation table to plus in OLS?, or Positive correlations to dependent variable, but negative coefficients are clear enough? I can add another answer here, if need be. | |
| Feb 23, 2015 at 23:01 | comment | added | whuber♦ | @gung I do not see there any explicit answer to this question, which asks us to compare correlation coefficients to multiple regression coefficients. Although I am in complete agreement that answers to this question have appeared (in many places), I am not sure that it is sufficiently obvious to a neophyte that those threads truly address the same question. You could convince me otherwise by providing a link to an obvious duplicate. | |
| Feb 23, 2015 at 22:56 | comment | added | gung - Reinstate Monica | @whuber, do you see something in this thread that I don't? This is a FAQ. I don't see anything here to be explained that doesn't already exist elsewhere on the site. The linked thread does not even mention multicollinearity. | |

The correlation between Lev & Size is .438. That may not be 'problematic' multicollinearity, but it could still cause the sign to flip in the same way as described at the linked thread.

specifically related to sign change when there does not seem to be a multicollinearity issue. Also, I am not an expert in statistics, and I would appreciate an answer in simpler language so I can better understand. Thanks

If you still have a question afterwards, come back here & edit your Q to state what you have learned & what you still need to know. Then we can provide the information you need without just duplicating material elsewhere that already didn't help you. | |
