At this time of year, when final exams and final class projects are being assigned, I doubt anyone will do your work for you, but if you post your data and what you have managed to accomplish so far, perhaps someone will give you a hint or two.

Also, a little context would be useful. What problem are you trying to solve?

People starting "from scratch" may want to know the reference for these formulas. These are equations 4.35 (p. 104), 4.34 (p. 103) and 4.33 (p. 103), copied from the monograph

Härdle, W., Müller, M., Sperlich, S., and Werwatz, A. (2004), Nonparametric and Semiparametric Models, Berlin: Springer.

Have you even tried? If so, show us what you have attempted.

Someone throwing me a general question phrased like that generally gets a billing invoice later.

The formula implies the existence of n value pairs for variables Y and X plus what appears to be a scaling factor m. So where are the values you want this applied to?

SAS has several procedures that uses splines Transreg, GAM TPSpline plus graphics options.
