Additional Splines in Excel - Bessel Spline, One Way (monotonic) spline
This demonstrates how to add several types of splines to Microsoft Excel with an add-in named Data Curve Fit Creator Add-in. In particular we show here the "Bessel spline" and a "One Way" (monotonic) spline. Both of these splines are similar to a cubic spline but can be better behaved (fewer unwanted wiggles and oscillations in the curve).
