Journal Article: A multivariate model for discrimination methods (1986)

Abstract: We describe a multivariate model for a certain class of discrimination methods in this paper and discuss a multivariate Euclidean model for a particular method, the triangular method. The methods of interest involve the selection of grouping of stimuli drawn from two stimulus sets on the basis of attributes invoked by the subject....

Journal Article: Fractional factorials in product development (1985)

Abstract: Response surface designs minimize cost by reducing the number of experimental formulations required to study a particular product characteristic. The response surface designs presented by Mullen and Ennis (1979) worked with a maximum of 5 variables. However, researchers are often faced with the question of how to handle a problem which has a...

Journal Article: Looking at innovation strategies (1985)

Abstract: For the past two decades, critics have pointed to a decline in innovative spirit in U.S. industry. Many writers have offered evidence which they feel documents this decline; many others have postulated hypothesis in an effort to understand the life cycle of the innovation process and its interaction with other environmental cycles. Several...

Journal Article: Theoretical aspects of sensory discrimination (1985)

Abstract: Discrimination methods are commonly used in research on the chemical senses. Chemosensory stimulation often leads to multivariate sensations. A multivariate theory for a class of discrimination techniques is described here along with a discussion of the practical implications of the theory to experimenters. One of the most important findings is that the probability...

Journal Article: The effect of dimensionality on results from the triangular method (1985)

Abstract: Methods to measure differences between complex stimulus sets (such as foods and beverages) are numerous One of the most commonly used procedures in food and beverage sensory research is the triangular method. A comparison of unidimensional and multidimensional normal models for the triangular method using Monte Carlo simulation showed that the expected subject...
