weight1 {OWEA}R Documentation

Implementation of Newton's method, Part 1.

Description

A function that optimizes weights for a given design using newton's method

Usage

weight1(opt, x, t, g_part, w0, infor_design, ...)

Arguments

opt

Integer. opt=0 means D-optimal, opt=1 means A-optimal.

x

Matrix, the design at current stage.

t

Integer. Number of levels of treatment.

g_part

Matrix. Contrast matrix. Its column numbers must match the row number of information matrix.

w0

Numeric Vector. Initial weights.

infor_design

Function. A function for calculating information matrix.

...

other necessary control parameters

Value

A numeric vector of optimized weights.
