BUS 660 Topic 2 Time Series Analysis and Forecasting - Homework

Problem 6-09: With the gasoline time series data from the given table, show the exponential smoothing forecasts using a = 0.1. a. Applying the MSE measure of forecast accuracy, would you prefer a smoothing constant of a = 0.1 or a = 0.2 for the gasoline sales time series? Do not round your interim computations and round your final answers to three decimal places. b. Are the results the same if you app y MAE as the measure of accuracy? Do not round your interim computations and round your fina...
