DUMMY COVARIATES IN CUB MODELS

Statistica, 2008, vol. 68, issue 2, 179-200

Abstract: In this paper we discuss the use of dummy variables as sensible covariates in a class of statistical models which aim at explaining the subjects’ preferences with respect to several items. After a brief introduction to CUB models, the work considers statistical interpretations of dummy covariates. Then, a simulation study is performed to evaluate the power discrimination of an asymptotic test among sub-populations. Some empirical evidences and concluding remarks end the paper.
