Consonance Analysis Module

ITAM - Delphi Intelligence - UV
CONS is a package with a graphical interface that performs Consonance Analysis. This procedure is an 
approach useful for evaluating the consistency of the measurements performed by a panel of people 
involved in sensory evaluation. It makes use of several uni and multivariate techniques either graphical 
or analytical. The procedure helps evaluate the linearirty of an attribute with respect to the panel 
performance. If there is evidence that an attribute is not linear then this information could be used to 
improve the evaluation of such characteristic. The method also helps detect whether some members of 
the panel deviate from the rest. A critical tool for this procedure is Principal Components Analysis.
