Conjoint analysis oparta na modelach IRT w zagadnieniu optymalizacji produktów bankowych
An IRT-approach for conjoint analysis for banking products preferences

Summary/Abstract: Conjoint measurement and conjoint analysis have common underlying psychometric and statistical assumption concerning axioms of additivity and two-way frame of reference in preference measurement. However, whereas the former concept is widely used in fundamental measurement of subject times × object times dominance structures as in IRT and Rasch measurement models, the latter is utilized in a broad familiy of object times object dominance structures in both compositional (i.e. Thurestone case III and V) as well as decompositional preference measurement models. These two traditions are rarely combined in one measurement model and research design that integrates subject times × object times object measurement. Empirical analysis will be based on the resarch on banking products prefferences among family members.
