In cds: Constrained Dual Scaling for Detecting Response Styles

Quadratic monotone spline basis function for given knots.

Description

Calculate basis functions for monotone quadratic splines.

Usage

ispline(xvec, tvec = c(0, 0.5, 1), intercept = TRUE)

Arguments

xvec	Vector at which to evaluate the basis functions.
tvec	Vector of spline knots: lower endpoint, interior knot, upper endpoint.
intercept	Logical; should an intercept be included or not?
