Suppose you estimate the following regression equation:
hat(Y)=12 3.2x_(1)-4.6x_(2)
First, what is the best interpretation of the slopes?
If x_(1) increases one unit, Y increases 3.2 units, holding x_(2) constant. If x_(2) increases one unit, Y decreases 4.6 units, holding x_(1) constant.
If x_(1) increases 3.2 units, Y increases by 1 unit, holding x_(2) constant.
