The mean value of the logarithmic hindcasting error for each dataset is plotted against the hindcasting horizon , in years. An error of , for example, indicates that the predicted value is three times as big as the actual value. The longest data-sets are: PrimaryAluminum (green), PrimaryMagnesium (dark blue), DRAM (grey), and Transistor (red).
