splinesBasis {ivmte}

Evaluating splines basis functions

Description

This function evaluates the splines basis functions. Unlike the bSpline in the splines2 package, this function returns the value of a single spline basis, rather than a vector of values for all the spline basis functions.

Usage

splinesBasis(x, knots, degree, intercept = TRUE, i, boundary.knots = c(0, 1))

Arguments

x

vector, the values at which to evaluate the basis function.

knots

vector, the internal knots.

degree

integer, the degree of the splines.

intercept

boolean, default set to TRUE. This includes an additional component to the basis splines so that the splines are a partition of unity (i.e. the sum of all components equal to 1).

i

integer, the basis component to be evaluated.

boundary.knots

vector, default is c(0, 1).

Value

scalar.
