A cubic spline is a smooth 3-order polynomial function that is piecewise-defined, and possesses a high degree of smoothness at the knots where the polynomial pieces connect.

A cubic spline is a smooth 3-order polynomial function that is piecewise-defined, and possesses a high degree of smoothness at the knots where the polynomial pieces connect. The most common cubic splines are Hermite, B-splines and Bezier splines.

Python: Cubic Spline Regression for a time series data

I have the data as shown below. I want to find a CUBIC SPLINE curve that fits the entire data set (link to sample data). Things I've tried so far: I've gone through scipy's Cubic Spline Functions, but all of them are only able to give results at a…

Evaluating python's UnivariateSpline on complex data

I used scipy to interpolate some real data. I wished to evaluate fitted spline on some complex data, is there some trick to force scipy to do it? If not, are there some python packages that provide this functionality? import scipy.interpolate as…
