piecewise_poly_basis_fun: Truncated Piecewise polynomial basis

In cshannum/unequalgroupoutlier: Anomaly Detection in Unequal Length Functional Data (Title Case)

Description

Truncated Piecewise polynomial basis

Usage

piecewise_poly_basis_fun(x, int_knots, p)

Arguments

x	A vector of a predictor variable.
int_knots	A vector containing the interior knots.
p	A value specifying the degree of the polynomial.

Value

A matrix consisting of (x_i - k_j)^p if x_i > k_j or 0 otherwise for i = 1,...,n and j = 1,... k. Where n equals the length of x and k equals the length of int_knots.
