It is common practice to log-transform response times before analyzing them with standard factor analytical methods. However, sometimes the log-transformation is not capable of linearizing the relation between the response times and the latent traits. Therefore, a more general approach to...

The present paper investigates estimation under the hypothesis of homogeneity or independence for a two-way contingency table. A family of optimality criteria (distances) is introduced of which well-known criteria such as maximum likelihood, Pearson- and Neyman chi-square. The Kullback-Liebler...

The authors review current developments in experimental design for conjoint analysis and discrete choice models emphasizing the issue of design efficiency. Drawing on recently developed optimal paired comparison designs, theoretical as well as empirical evidence is provided that established...
