Does a smoothing constant of 0.2 or 0.4 appear to provide more accurate forecasts based on MSE?
A smoothing constant of 0.4 is better than a smoothing constant of 0.2 since the MSE is greater for 0.4 than for 0.2.
A smoothing constant of 0.2 is better than a smoothing constant of 0.4 since the MSE is greater for 0.2 than for 0.4.
A smoothing constant of 0.2 is better than a smoothing constant of 0.4 since the MSE is less for 0.2 than for 0.4.
A smoothing constant of 0.4 is better than a smoothing constant of 0.2 since the MSE is less for 0.4 than for 0.2.
