make_knots {profoc}

Create a vector of knots for splines

Description

This function creates a knot vector for splines. The knots are distributed according to a beta distribution. The first input defines the number of inner knots. The total number of knots is n + 2 * order.

Usage

make_knots(n, mu = 0.5, sig = 1, nonc = 0, tailw = 1, deg = 1)

Arguments

n

Number of knots

mu

Beta distribution location parameter

sig

Beta distribution scale parameter

nonc

Beta distribution noncentrality parameter

tailw

Tailweight

deg

Degree of splines
