Q1) Simple Moving Average, Weighted Moving Average \& Exponential Smoothing: The observed number of demands for ten periods is given in the table below. Q2) Double Exponential Smoothing (Holt's Trend/Model) The Actual Demand for six periods is given in the table below. a) Forecast the demand using the following methods: - Simple Moving Average (three-period moving average: SMA(3) - Weighted Moving Average (three-period moving average): WMA(3) a) Use the Double Exponential Smoothing (Holt's Trend/Model) to find the forecast value for the given six Assume: w1=0.5,w2=0.3,w3=0.2 periods and for periods 7&8. Assume: =0.1,=0.2&S0=65,G0=0 - The Exponential Smoothing. b) Calculate the mean squared error (MSE). Assume: =0.2&F1=22 b) Calculate the mean squared error (MSE) for all methods. Please explain which method performs better
