Multivariate and Probabilistic Analyses of Sensory Science Problems
by Jean-Fran& ccedil;ois Meullenet

Multivariate and Probabilistic Analyses of Sensory Science Problems explains the multivariate and probabilistic methods available to sensory scientists involved in product development or maintenance.

The techniques discussed address sensory problems such as:

  • panel performance
  • product profiling
  • exploration of consumer data, including segmentation
  • identifying drivers of liking

Multivariate and Probabilistic Analyses of Sensory Science Problems offers simple, easy-to-understand explanations of difficult statistical concepts and provides an extensive list of case studies with step-by-step instructions for performing analyses and interpreting the results.

Coverage includes:

  • a refresher on basic multivariate statistical concepts
  • use of a common data set throughout the text
  • summary tables presenting the pros and cons of specific methods and the conclusions that may be drawn from using various methods
  • sample program codes to perform the analyses and sample outputs
