The Preference Mapping methodology combines information from both sources: end-consumer preferences and expert panel description. The PREFMAP, with the interpretation given by the preference map is an aid to interpretation and decision-making which is potentially very powerful since it allows preference data to be linked to objective data. For cluster 2 we have an anti-ideal point. The preference map allows to quickly interpret the results. What success can I expect from my product? For instance, it ignores the fact that one assessor may rate attributes on wider scales or has a systematic higher rating than other assessors. It consists in We then store the centroids of the clusters for the last step of the analysis. XLSTAT: who are we? In our situation, each assessor corresponds to one table (products - attributes). If the CATA survey includes preference data, this tool can be used to identify drivers of liking or on the opposite, attributes that consumers consider as negative. As a general method, MFA can also be used to uncover information on the relationships between different subsets of sensory attributes. facilitate the interpreting of results. Then, you need to setup the compulsory data fields (Y and X the linear regression). The thicker lines corresponds to the direction in which the preference increases, and the thinner ones to the direction in which it diminishes. A preference map is a decision support tool in analyses where a configuration of objects has been obtained from a first analysis (PCA . However, it offers significance testing which makes the investigation of product differences across attributes more precise. There are two different preference mapping methods: Internal Preference Mapping (IPM) is based on PrincipalComponent Analysis (PCA) to allow identifying which products correspond to groups of consumers. Difference experiments, where overall differences among products are evaluated by assessors. Choosing an appropriate Sensory data analysis tool.
