Technical Report: Indices of Sensory Difference: R-Index and d’

ABSTRACT Discrimination methodologies are used to investigate similarities and differences among variants of manufactured products. Applications typically involve cost savings, storage and product improvements. A researcher often requires more information than a simple test of significance which can be readily changed by simply altering the sample size used. In many cases, estimation of the...
