The interpretation of the slope coefficient in the model, 1n (Yi) = B0 + B1 1n (Xi) + ui, is as follows: A change in X by one unit is associated iwth B1% change in YA change in X by one unit is associated with 100B1% change in YA 1% change in X is associated with B1% change in YA 1% change in X is associated with a change in Y of 0.01B1
