Hello
I am looking for a function to create an Integrated (I) spline basis,
somehting similar to the likes of 'bs' and 'ns'. I have come across the
funcitons,
fda::eval.monfd Values of a Monotone Functional Data
Object
fda::/.fd FDA internal functions
fda::monfn Evaluates a monotone function
fda::smooth.monotone
Monotone Smoothing of Data
mgcv::mono.con Monotonicity constraints for a cubic
regression spline
splines::backSpline
Monotone Inverse Spline
stats::isoreg Isotonic / Monotone Regression
but none of these are specifically for an I-spline. Any help would be
much appreciated.
