Chemometrics, econometrics, psychometrics—How best to handle hedonics?

Sensory scientists may choose models from multiple disciplines for analyzing the relationship of consumer hedonics to the physical, chemical and perceptual characteristics of sensory objects. Two characteristics of sensory hedonics, satiety and differential variation, severely constrain the ability of models that cannot process these characteristics to successfully model this relationship. Overestimation of models with an excessive number of parameters is also shown to be a serious problem.
