Abstract
In this paper, Poisson regression models with three binary predictors are considered. These models are applied to rule-based tasks in educational and psychological testing. To efficiently estimate the parameters of these models locally D-optimal designs will be derived. Eight out of all 70 possible saturated designs are proved to be locally D-optimal in the case of active effects. Two further saturated designs which are the classical fractional factorial designs turn out to be locally D-optimal for vanishing effects.
