Reseña del libro "multivariate data analysis in sensory and consumer science"
this book is about sensometrics: the statistical analysis of data from sensory and consumer science. sensory and consumer science is a broad field, comprising research in food, drinks, personal care products, tobacco, cleaning agents, etc. before a product is to be launched on the market it is often tested by sensory panels. the analytical panels with trained judges assess the products on a great number of specific properties using sensory profiling techniques. in consumer tests the focus is on the acceptance of certain products or the preference for a specific product. following an introduction to sensory and consumer science and the special types of data abundant in these fields, eleven chapters address four themes in sensometrics: individual differences between the assessors in a sensory panel, the measurement level of the collected data and non linear analyses, sensory-instrumental relations, and time-intensity data analysis. the analyses are performed using, among others, procrustes analysis, multidimensional scaling, principal component analysis, canonical analysis, redundancy analysis, and biplots.
