The interpretation of the slope coefficient in the model YB2

The interpretation of the slope coefficient in the model Y-B2 In X u is as follows: a (a) 1% change in X is associated with a 32% change in Y (b) 1% change in X is associated with a change in Y of (c) change in X by one unit is asociated with a 10032% change in Y (d) (hange in X by one unit is associated with a .½ change in Y Question 8 The interpretation of the slope (oefficient in the model In Yi = 31 + 32X-+ t4 is as follows: a (a) 1% change in X is associated with a 32% change in Y (b) change in X by one unit is associated with a 100 % change in Y (e) 1% change in X is associated with a change in Y of (d) change in X by one unit is associated with a 2 change in Y Question 9 The interpretation of the slope coefficient in the model InY, 1+B2 In Xiu, is as follows: a (a) 1% dange in X is associated with a .32% dange in Y (b) change in X by one unit is associated with a change in Y (c) change in X by one unit is associated with a 10032% dange in Y. (d) 1 % change in X is associated with a change in Y of 100

Solution

7. This is a lin-log model and the interpretation of this slope is (B) i.e 1% change in X leads to a change Y of B₂/100.

8. This is a linear model and the interpretation of this slope is (D) i.e 1 unit change in X leads to B₂ change in Y.

9. This is a double log model and the interpretation of this slope is (A) i.e 1% change in X is associated with a B₂ % change in Y.
