The Constrained Median: A Way to Incorporate Side Information in the Assessment of Food Samples
A classical problem in the field of food science concerns the consensus evaluation of food samples. Typically, several panelists are asked to provide scores describing the perceived quality of the samples, and subsequently, the overall (consensus) scores are determined. Unfortunately, gathering a la...
