Suppose you use Winter's forecasting method on historical data from Q1 2010 to Q4 2018. You obtain the following data for time t = quarter 4 2018: L t= 1065 T t = 15 S t = 0.95 S_{t-1} = 0.9 S_{t-2} = 1.2 S_{t-3) = 1.1 Exponential smoothing parameters: alpha=0.2 beta = 0.3 gamma = 0.2 What is the absolute value of the difference between the forecasts for quarter 2 2020 and quarter 4 2021 with Winter's method?
