Preference Mapping (PREFMAP) Build decision making maps to:
• Improve or develop products • Position products in comparison with competitors’ products• Reach a target market
Preference mapping = a powerful tool to optimize product acceptability.
XLSTAT-MX offers several regression models to project complementary data on the objects maps:
• Vector model,• Circular ideal point model,• Elliptical ideal point model,• Quadratic ideal point model.

Generalized Procrustes Analysis (GPA) GPA compares the proximity between
the terms that are used by different experts to describe products.

Multiple Factor Analysis (MFA) MFA is a generalization of PCA
(Principal Component Analysis) and MCA (Multiple Correspondence Analysis).
MFA makes it possible to:• Analyze several tables of variables
simultaneously, • Obtain results that allow studying the
relationship between the observations, the variables and tables.

Wine 13 is in the direction of the two quality variables and is therefore the wine of preference.

Penalty analysis Identify potential directions for the
improvement of products, on the basis of surveys performed on consumers or experts.
Two types of data are used:• Preference data (or liking scores) for a product or for a characteristic of a product
• Data collected on a JAR (Just About Right) scale
![Page 15: Benefits Key Features and Results. XLSTAT-MX functions](https://reader035.vdocuments.site/reader035/viewer/2022062216/56649e195503460f94b05868/html5/thumbnails/15.jpg)
Penalty analysisA type of potato chips is evaluated:
By 150 consumersOn a JAR scale (1 to 5) for 4 attributes:
• Saltiness, • Sweetness, • Acidity, • Crunchiness.
And on an overall liking (1 to 10) score scale

Penalty analysis
Mean of Liking for JAR – Mean of Liking for too little and too much

Semantic differential charts The semantic differential method is a
visualization method to plot the differences between individuals' connotations for a given word.
This method can be used for:• Analyzing experts’ agreement on the
perceptions of a product described by a series of criteria on similar scales
• Analyzing customer satisfaction surveys and segmentation
• Profiling products

TURF analysis TURF = Total Unduplicated Reach and
Frequency method
Highlight a line of products from a complete range of products in order to have the highest market share.
XLSTAT offers three algorithms to find the best combination of products

TURF analysis 27 possible dishes 185 customers
"Would you buy this product?" (1: No, not at all to 5: Yes, quite sure).
The goal is to obtain a product line of 5 dishes maximizing the reach

Product characterization Find which descriptors are discriminating
well a set of products and which the most important characteristics of each product are.
All computations are based on the analysis of variance (ANOVA) model.
Check the influence on the scores of attributes of:
• Product• Judge
• Session• Judge*Product

DOE for sensory data analysis Designing an experiment is a
fundamental step to ensure that the collected data will be statistically usable in the best possible way.
![Page 27: Benefits Key Features and Results. XLSTAT-MX functions](https://reader035.vdocuments.site/reader035/viewer/2022062216/56649e195503460f94b05868/html5/thumbnails/27.jpg)
DOE for sensory data analysis Prepare a sensory evaluation where
judges (experts and/or consumers) evaluate a set of products taking into account:
• Number of judges to involve• Maximum number of products that a judge
can evaluate during each session• Which products will be evaluated by each of
the consumers in each session, and in what order (carry-over)
Complete plans or incomplete block designs, balanced or not.
Search optimal designs with A- or D-efficiency
