b_rcs_prime

knots

<p>function that derives the first derivative of the restricted cubic splines 
for a value/vector of values, given the knots</p>


Functions for generating variants of curves:
restricted cubic spline, periodic restricted cubic spline,
periodic cubic spline. Periodic splines can be used to model data
that has periodic nature / seasonality.
