Two independent methods of forecasting based on judgment and experience have been prepared each month for the past 10 months. The forecasts and actual sales are as follows: Month Sales Forecast 1 Forecast 2 1 770 771 769 2 789 785 787 3 794 790 792 4 780 784 798 5 768 770 774 6 772 768 770 7 760 761 759 8 775 771 775 9 786 784 788 10 790 788 788 (a). Compute the MSE and MAD for each forecast. Does either forecast seem superior? Explain. (b). Compute MAPE for each forecast.
21. Consider a firm subject to quarter-to-quarter variation in its sales. Suppose that the following equation was estimated using quarterly data for the period 2011–2018 (the time variable goes from 1 to 32). The variables D1, D2, and D3 are, respectively, dummy variables for the first, second, and third quarters (e.g., D1 is equal to 1 in the first quarter and 0 otherwise). Qt =a+bt+c1D1+c2D2+c3D3 The results of the estimation are presented here: a. Calculate the intercept in each of the four quarters. What do these values imply? b. Use this estimated equation to forecast sales in the fourth quarter of 2019.

Your economics textbook hit the market with a bang, selling 10856 copies in its debut year. The publisher is optimistic, forecasting a sales increase of 11% annually for the next 3 years, followed by a growth spurt of 19% in the fourth year. Calculate the expected sales figures after 4 years of growth.

Question 2 a) Sketch two separate time series on two different axes with the following features: i. The first time series should violate only one out of the three requirements for stationarity. ii. The second should violate at least two of the three requirements for stationarity. State each violation mathematically and explain it conceptually. Label your graphs appropriately and explain exactly how these violations are being depicted in your time series plots. b) Can you forecast either of these time series variables using the AR models you studied in this course? Explain in detail how you would do this and outline any limitations or drawbacks of this approach. c) Can you regress one of these time series variables on the other? What kind of results will you get if you do so? Give a well-thought-out answer based on everything you have learnt about this topic in this course.
5. Exercise 5.5 A firm experienced the demand shown in the following table. Fill in the table by preparing forecasts based on a five-year moving average, a three-year moving average, and exponential smoothing (w = 0.9 forecasts may be begun by assuming Y t+ F Yt •) and w = 0.3 ). (Note: The exponential smoothing Moving Average Actual Demand (5-year) (3-year) Exponential Smoothing (W = 0.9) Year (W = 0.3) 2000 900 2001 885 900 900 2002 875 2003 870 887 ▼ 2004 870 877 ▼ 2005 875 880 872 Y 2006 885 875 872 2007 900 875 877 2008 920 880 887 - 2009 945 890 902 Y 2010 905 922 The following table shows the square errors, (Y; - T1-) , for forecasts from 2005 through 2009.
