Optimal designs for third-order interactions in paired comparison experiments
Eric Nyarko
It is shown how by not losing information on higher order interactions, optimal paired comparison designs involving alternatives of either full or partial profiles to reduce inform…
Optimal Paired Comparison Block Designs
Eric Nyarko
For paired comparison experiments involving competing options described by two-level attributes several different methods of constructing designs having block paired observations u…
Optimal Paired Comparison Designs for Third-Order Interactions
Eric Nyarko
In psychological research often paired comparisons are used in which either full or partial profiles of the alternatives described by a common set of two-level attributes are prese…
Optimal Designs for Second-Order Interactions in Paired Comparison Experiments with Binary Attributes
Eric Nyarko, Rainer Schwabe
In paired comparison experiments respondents usually evaluate pairs of competing options. For this situation we introduce an appropriate model and derive optimal designs in the pre…
