BaseNorm {pkmon}

Normalized spline basis

Description

Computes the k-monotone discrete splines from Lefevre and Loisel (2013).

Usage

BaseNorm(k, J)

Arguments

k

Degree of monotony

J

maximum support of the splines

Value

matrix Q with J+1 rows and J+1 columns with Q(i,j)=Q_j^k(i-1)=C_{j-i+k-1}^{k-1}, where C represents the binomial coefficient.
