CHAPT. 10 – When products are described by a mix of liking and external information

Posted by | No Tags | Non classé | Pas de commentaire

“…consumers are more involved in the sensory task. Indeed, in such tasks, and additionally to liking ratings, consumers are also asked to provide in- formation on how they perceive the products, and how they would like them. Such information is either acquired directly (Ideal Profile Method [IPM]), or as deviation from the ideal point (Just About Right [JAR] scale). Although this “ideal” information is of utmost importance for product optimization, it is questionable, as it comes from consumers who are rating fictive products. Before analyzing such data, when possible, it is recommended to check for their consistency. This can be done by using the ConsistencyIdeal function of the SensoMineR package.
