knotfixfit: Knots locations selection

In Alexestat/splineSelection: Automatic model selection in spline-based regression.

Description

Provides internal knots locations in spline-based models for a fixed number of knots.

Usage

knotfixfit(
  x,
  y,
  nknots,
  delta,
  degree,
  b.knots = c(min(x), max(x)),
  bspline = TRUE
)

Arguments

x	Vector of function arguments.
y	Vector of function values.
nknots	Number of internal knots.
delta	Minimal distance value between two consecutive knots.
degree	Degree of the spline basis.
b.knots	External knots vector. Default is the (min(x),max(x)).
bspline	Logical value. If TRUE, B-spline is fitted. Else, natural splines.

Value

A list with selected internal knots, mean square error and fitted model.
