Assessing sensory panel performance using generalizability theory

摘要

Generalizability theory provides a framework for assessing panel reliability, both for the panel as a whole and for individual panellists. The variability of the sensory panel scores is split up into products, panellists, replications, and interactions between these terms. Reliability is defined as product variance over total variance. Coefficient G only includes terms including product in the denominator and focusses on the ordering of the product scores.
