D-Optimal Design for the Rasch Counts Model with Multiple Binary Predictors [PDF]
British Journal of Mathematical and Statistical Psychology Volume
73, 2020, Issue 3, p. 541-555, 2018 In this paper, we derive optimal designs for the Rasch Poisson counts model and the Rasch Poisson-Gamma counts model incorporating several binary predictors for the difficulty parameter. To efficiently estimate the regression coefficients of the predictors, locally D-optimal designs are developed. After an introduction to the Rasch Poisson counts model
