Workshop summary: data analysis workshop: getting the most out of just-about-right data.

摘要

Just-about-right (JAR) scales have been widely used in consumer tests of foods and beverages. This workshop considered statistical methods for analysis of JAR scales. Topics include Thurstonian ideal point modelling versus deterministic modelling of JAR scale ratings; application of multivariate adaptive regression splines (MARS) to analysis of JAR scale data; JAR directionality and the wandering scale unit; methods for comparing JAR score distributions for matched and independent product pairs; segmentation of the consumer panel in analysis of JAR data; and sensory optimisation and reverse engineering with JAR scales.
