Thanks for that. I'm not familiar with the concept of splines, and am looking for a gentle introduction to the area, in order to move beyond using quadratic and cubic etc terms in my models.

In official Stata there is -mkspline- which makes variables containing the linear or restricted cubic splines, which you can than enter in any estimation command. An introductory text on these is Harrell (2001). Is that what you are looking for? - -- Maarten Harrell Jr., F. E. 2001.
