measures the proportion of variation in Y that is explained by X1 and X2.
measures the proportion of variation in Y that is explained by X1 holding X2 constant.
will have the same sign as b1.
Explanation / Answer
Sol:
Coeffcient of multile determniation tells the prportion of variation in y explained by independent varables.
For ex if in multiple regresison equation
r sq=0.80
Intrepretaion:
80% variation in y is expalined by x1 and x2
ANSWER:B
measures the proportion of variation in Y that is explained by X1 and X2.
measures the proportion of variation in Y that is explained by X1 and X2.
