Q3(33p). Build a demand forecasting problem using Simple Exponential Correction Approach for Largely Varying Demand Model. This very moment is the end of period 23. Use 4 different \(\alpha \) values. Calculate all possible demands including past periods. Draw graphs of 5 demand behaviors (1 eventuated and 4 from calculations) in the same chart space, and interpret results. Calculate error margins using Mean Absolute Deviation (MAD), Mean Squared Error (MSE) and Mean Absolute Percentage Error (MAPE) techniques.
