S_weight function

Newton Raphson method to get optimal weights

Newton Raphson method to get optimal weights for given design points "X".

S_weight(X, T, e1, f, ...)

Arguments

• X: A numeric vector. K dose levels for a given design
• T: A numeric vector. Model parameter values
• e1: Numeric. Threshold to stop the iteration.
• f: A character. D_weight for D-optimal weight; c_weight for c-optimal weight; DD_weight for Ds-optimal weight
• ...: Default.
