Data Smoothing by Interpolating Cubic Splines R package ICSsmoothing version 1.2.10 We construct the explicit form of clamped cubic interpolating spline (both uniform - knots are equidistant and non-uniform - knots are arbitrary). Using this form, we propose a linear regression model suitable for real data smoothing.
