smallds1

A numeric vector. Model parameter values

A numeric matrix. Inverse information matrix

numeric. The number of model paraemters: 3, 4, 5 for the 3, 4, 5PL models respectively

order

This evaluates the sensitivity function of the D-optimality criterion at the given value of x
 for a specified model.

Obtain and evaluate various optimal designs for the 3, 4, and 5-parameter logistic models. The optimal designs are obtained based on the numerical algorithm in Hyun, Wong, Yang (2018) <doi:10.18637/jss.v083.i05>.
