c_weight {Opt5PL}

One iteration to run Newton Raphson to get c-optimal weights

Description

This is a sub-part of running Newton Raphon method to search c-optimal weights for the given design points. This is function probvides the obtained c-optimal weights after one iteration of Newton Raphson method.

Usage

c_weight(W, T, X, d, p, order, UB, I)

Arguments

W

A numeric vector. The first K-1 weights for a given design

T

A numeric vector. Model parameter values

X

A numeric vector. K dose levels for a given design

d

Numeric. Step adjustment

p

Numeric. Define EDp

order

Numeric. The number of model paraemters

UB

Numeric. The upper bound of the design points

I

A numeric matrix. Identity matrix.
