Statistical - Cubic Regression (Cubic Spline Fit) ?

[rprosperi]

I'm not sure if there is interest in the 71B User Library Cubic Spline interpolation program I mentioned, however it's taken weeks to find it, and since I have it now, here's a scan of the user library program description, including an overview, a little theory review, sample problem, sample program run output and BASIC program listing.

Note: The HP-71B MATH PAC ROM (or JFG's enhanced 2B version) must be installed for this to work.
