3 Fitting Data
3-74
The data and fits are shown below. The default abscissa scale was increased to
show the fit behavior beyond the data limits. You change the axes limits with
Tools->Axes Limit Control menu item.
Note that the default smoothing parameter produces the smoothest curve. As
the smoothing parameter increases beyond the default value, the associated
curve approaches the cubic spline curve.
The cubic spline and default
smoothing spline results
diverge at the end points.
The cubic spline and default
smoothing spline results are
similar for interior points.
