c_weight function

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

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.

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.
