We derive locally D- and ED p -optimal designs for the exponential, log-linear and three-parameter emax models. For each model the locally D- and ED p -optimal designs are supported at the same set of ...

Comparing regression coefficients between models when one model is nested within another is of great practical interest when two explanations of a given phenomenon are specified as linear models. The ...

For engineering applications, there are three approaches to consider: the linear, bias-voltage plus resistor equivalent, a quadratic equation, and an exponential equation.
