Monthly demand for a hot pizza restaurant is given as follows for 1 year (12 months). Estimate the demand including the next two months (13 and 14) by using Holt's and Exponential Smoothing methods. Compare the methods with MSE, MAD, and MAPE metrics, and discuss the superior method.
Use alpha=0.05 and beta=0.1 for Holt's model and use alpha=0.3 for exponential smoothing model. Hint: Level and trend in Holt's method could be obtained with regression. L0 in exponential smoothing is the average demand for the 12-month period.
