Create a time series model (with level, linear trend, and seasonal components) for purposes of forecasting daily demand at Penguin for April 9-27, including a margin of uncertainty for each day’s forecast. Note, assume that forecast errors are normally distributed. Calculate: • Deseasonalization (Deseas) • D-Bar • S-Bar • Seasonal (Seas) Factor • Forecast • Absolute Error • Slope • Intercept • Mean Absolute Deviation (MAD) • Margin of Uncertainty • Upper and Lower Forecasts per day
