1. Use 3 and 4-month moving average on all the data and plot the averages and the prices.
2. Use 3 and 4-month weighted moving average on all the data and plot the averages and the prices. (0.4, 0.3, 0.3 for 3 month; and 0.5, 0.3, 01, and 0,1 for 4 month)
3. Compute the forecasts for each month using exponential smoothing, with an initial forecast for January of $1.85. Use = .2, then = .4, and finally = .5.
4. Compute the forecasts for each month using trend adjusting exponential smoothing, with an initial forecast for January of $1.85 and trend $0.2. Use = .2, and = .4.
5. Develop a regression relationship.
6. Compare forecasting methods using MAD, MSE, and MAPE.
