Subject: Inconsistent Beta Coefficient Sign Between Multiple and Simple
Content-Type: text/plain; charset=us-ascii
I am conducting a multiple Linear regression with 3 predictors, all variables
are continuous and N=51. Before doing linear regression analysis, I did
first a simple linear regression and found that all the predictors have
positive correlation with the outcome variable.
Surprisingly, when I did the multiple linear regression, one of the
predictors have negative B unstandardized coefficients, with less than -1.0
coefficient, VIF value less than 10, and these are no indication of
Is there anything wrong with the result? Please kindly give any advice how
to explain this case.
