Chapter 16, Problem 42PS

In forecasting a quarterly time series over the five-year period from the first quarter of 2013 through the fourth quarter of 2017, the exponential tread forecasting equation is given by

$\log {\hat{Y}}_i=3.0+0.10X_i-0.25Q_1+0.20Q_2+0.15Q_3$

Where quarter zero is the first quarter of 2013. Take the antilog of the appropriate coefficient from this equation and interpret the

a. $Y$ intercept, ${\text{<mover accent="true"> b <mo> ^ </mo> </mover>}}_0.$

b. quarterly compound growth rate.

c. second-quarter multiplier.
