Exponential smoothing with alpha = 0.4
MAPE for each year = [abs(error)/sales]*100
MAPE for total = average of MAPE for each year
For better comparison, error calculation has been done from period 3 which is to sync with 2 period moving average
2 period moving average
We can see 2 period moving average yields better results as it has lower MAPE

1. Exercise 5.1 The forecasting staff for the Prizer Corporation has developed a model to predict sales of its air-cushioned-ride snowmobiles. The model specifies that sales, S, vary jointly with disposable personal income, Y, and the population between ages 15 and 40,Z, and inversely with the price of the snowmobiles, P. Based on past data, the best estimate of this relationship is: where k has been estimated (from past data) to equal 100 If Y $13,000, Z- $1,200, and P...
