Given the table above, calculate 1. Simple Moving Average with n=2 2. Simple Moving Average with n=3 3. Weighted Moving average with weights 0.6 and 0.4 4. Weighted Moving average with weights 0.5,0.3, and 02 5. Exponential Smoothing with alpha =0.4 and F1=570 6. Calculate the MAD for each and tell me which is the best model. 7. The regression line y=ax+b, the residuals, and the forecast for the 7th and the 12th month. Is the model good? Given the table above, calculate 1. Simple Moving Average with n=2 2.
