Question 3 2.5 pts The interpretation of the slope coefficient in the model In(K)-A + ??.r o a change in X by one unit is associated with a B1 change in Y. o a 1% change in X is associated with a change in Y of 0.01 a change in X by one unit is associated with a81 100% change in Y. a 1% change in X is associated with a ?1 % change in Y DQuestion 4 2.5 pts To decide whetherr-A + ß, X-+ u or ln(X)-A, + ßiX, + u fts the data better, you cannot consult the regression RA2 because the regression R2 can be greater than one in the second model. o the TSS are not measured in the same units between the two models. O the slope no longer indicates the effect of a unit change of X on Y in the log-linear model. In(Y) may be negative for OkY

Explanation / Answer

3. a change in x by one unit is associated with B1 100%change in Y.

4. TSS are not measured in the same unit between two models.

R square depend on TSS and it is measured in different units on both models. This Rsquare will not give you accurate measure of goodness of fit. Models with different dependent variable are not comparable with R square.
