The dummy variable approach is a regression method that can be applied to map relationships between JAR and liking scores. The approach models the relationship between JAR and liking variables, estimates the mean drop of Overall Liking (OL) as a function of JAR scores and determines the drivers of liking. The dummy variable approach is a very flexible method that can be performed either for individual products or for all products to determine the effects of JAR attribute scores on Overall Liking.
