The smooth.spline function in R allows a tradeoff between roughness (as defined by the integrated square of the second derivative) and fitting the points (as defined by summing the squares of the r...

I'm having trouble getting scipy.interpolate.UnivariateSpline to use any smoothing when interpolating. Based on the function's page as well as some previous posts, I believe it should provide smoot...

I have a following model: coxph(Surv(fulength, mortality == 1) ~ pspline(predictor)) where is fulength is a duration of follow-up (including mortality), predictor is a predictor of mortality. T...

I'm looking for a way to make a line curve through a number of points. It would be preferable to use 3 points although I've considered that in order to give context to the angle of the line enterin...

I have a set of data points and would like to approximate them with a spline function. I used two different functions: splrep from scipy and a cubic spline function that I found here. The resul...

Given an arbitrary sequence of points in space, how would you produce a smooth continuous interpolation between them? 2D and 3D solutions are welcome. Solutions that produce a list of points at ar...

A brief background: I'm working on a web-based drawing application and need to draw 1px thick splines that pass through their control points. The issue I'm struggling with is that I need to draw e...
