Optimal designs for -factor two-level models with first-order interactions on a symmetrically restricted design region
Fritjof Freise, Rainer Schwabe
We develop -optimal designs for linear models with first-order interactions on a subset of the full factorial design region, when both the number of factors set to the hig…
Optimal Designs for Poisson Count Data with Gamma Block Effects
Marius Schmidt, Rainer Schwabe
The Poisson-Gamma model is a generalization of the Poisson model, which can be used for modelling count data. We show that the -optimality criterion for the Poisson-Gamma model…
Optimal designs for two-level main effects models on a restricted design region
Fritjof Freise, Heinz Holling, Rainer Schwabe
We develop -optimal designs for linear main effects models on a subset of the full factorial design region, when the number of factors set to the higher level is bounded.…
Optimal Designs for the Generalized Partial Credit Model
Paul-Christian Bürkner, Rainer Schwabe, Heinz Holling
Analyzing ordinal data becomes increasingly important in psychology, especially in the context of item response theory. The generalized partial credit model (GPCM) is probably the…
