D-OPTIMAL DESIGN FOR LOGISTIC REGRESSION MODEL WITH THREE INDEPENDENT VARIABLES

Non-linear models are of particular importance owing to their various applications in different fields. In this paper, considering D-optimal criterion, appropriate models were introduced and, based on a logistic regression model with three independent variables and dependence of information matrix on passive parameters, a locally D-optimal design was obtained for several specific states. It is noteworthy that certain designs with different points were presented and their subject optimality was calculated based on space of the parameters.
