spen_egcv:

Description

This function is only intended for an internal use.

Usage

spen_egcv(dim, x, y, w, h, QtyPerm, lambda, m, nforApp,
		 EGCVflag, agcv)

Arguments

dim

vector of sample size.

x

x-vector in smooth.pen.reg.

y

y-vector in smooth.pen.reg.

w

w-vector in smooth.pen.reg.

h

difference vector for x for internal use.

QtyPerm

Second order difference for x for internal use.

lambda

smoothing parameter input for smooth.pen.reg.

m

vector to store the prediction vector.

nforApp

Number of iterations for approximate GCV.

EGCVflag

Logical when GCV is needed.

agcv

Internal scalar. Set to 0. Stores the approximate GCV.

Value

Does not return anything. Changes the inputs according to the iterations.

Details

This is same as smooth.spline except for small changes.
