isplinebasis: Transform a given data into I-splines
Description
Inner function call to create I-splines based on the
user defined knots
and polynomial degree d
of the splines
Usage
isplinebasis(x, knots, d)
Arguments
x
a scalar or vector of values which will be transformed into splines
knots
a vector of knot values of the splines
d
the polynomial degree of the splines
Value
a matrix with for each value of x the corresponding spline values.
