Cubic Spline Regression Excel. Cubic splines are used to fit a smooth curve to a series of points with a piecewise series of cubic polynomial curves. But for a beam between simple supports y00x Mx EI where Mx varies linearly.

In XLSTAT three options are offered.
This is a demo of a free add-in for Microsoft Excel which adds cubic spline several other splines and linear interpolation to Excel. You can create a user defined function to calculate interpolated values of the gilt curve using a cubic spline. The value of the calculated spline value for the interpolated period will be 487. Extend the selection the left 2 spaces you need the select to be at least 3 cells wide.
