bspline: B-Spline Interpolation and Regression
Build and use B-splines for interpolation and regression.
In case of regression, equality constraints as well as monotonicity
requirement can be imposed. Moreover,
knot positions (not only spline coefficients) can be part of
optimized parameters too. User is provided with
functions calculating spline values at arbitrary points. This
functions can be differentiated to obtain B-splines calculating
derivatives at any point. B-splines of this package can
simultaneously operate on a series of curves sharing the same set of
knots. 'bspline' is written with concern about computing
performance that's why the basis calculation is implemented in C++.
The rest is implemented in R but without notable impact on computing speed.
