  Analyse d'un tableau ternaire d'évaluations sensorielles [Analysis of a three-way table of sensory evaluations]. Revue Statistique Appliquée,40, 45-58.
  In this paper, a procedure is presented to analyse a set of tables within the context of sensory evaluation. To study the performance of judges, a metric is introduced in which the optimality is realised for a fixed-effects model. This metric has the property to provide a coherent evaluation of judges. The characterisation of products is given by an analysis of the combined tables.

  A hierarchy of models for analysing sensory data. Food Quality and Preference, 6, 309-314.
  To analyse sensory profile similarity data produced by different assessors a three-level hierarchy of analysis is proposed consisting of averaging the similarity matrices, weighted averaging (i.e. STATIS, Lavit 1988), and differentially weighting (INDSCAL; Carroll & Chang, 1970). The successive component computation via deflation is proposed (which has been shown to be suboptimal, Carroll & Chang, 1970). Seven 8x8 matrices describing the similarities of yoghurts were analysed.
