Can you post the equations too please!

0.2 Problem Set 6 Calculate the simple three-month moving average forecast for April through December. What is the forecast for December? Calculate the weighted three-month moving average using weights of 0.50 (t-1), 0.30 (t-2), and 0.20 (t-3) for April through December. What is the forecast for December? Calculate the single exponential smoothing forecast for February through December using an initial forecast (F1-F-January) of 63. (Use alpha of 0.2) What is the forecast for December? Calculate the mean absolute deviation (MAD) for the forecasts made by each technique in April through December. Which forecasting method do you prefer?
