Given the multiple regression equation, ? = a+b1X1+b2X2, and the bivariate equation ? = a+bX1, why is the partial regression coefficient, b1,different from the regression coefficient, b, obtained by regressing Y on only X1?
What will be an ideal response?
This happens because X1 and X2 are usually correlated. In bivariate regression, X2 was not considered and any variation in Y that was shared byX1 and X2 was attributed to X1. However, in the case of multiple independent variables, this is no longer true.
