DetailsThese data provide one example of a case where a multivariate regression doesn't benefit from having multiple outcome measures, using the standard tests. Barrett (2003) uses this data to illustrate influence measures for multivariate regression models.
The taste and smell values are the mean ratings of 10 experts on some unknown scale.
