Note: Numbers without superscript indicate R2at sine 4, a = R2 at sine 3, b =R2 at sine 2, c = R2at sine1.
Figure 1. Example of over-fitting for N2 for Block One. The plot of Sine
2 is considered an appropriately fitted function while Sine 3 is
considered overfitted by the appearance of the fit line with high
frequencies being plotted.
