Appropriate Methods of Imputation for Consumer Hedonic Data
The challenge is to perform appropriate data imputation for 570 consumers, each of whom evaluates 6 brown breads in a 16-present-6 sensory-informed balanced incomplete block design. These data were previously analyzed and discussed . Data are available (i) in the R package sensory (see bbread), and (ii) on the Sensometrics Data Set Repository (see Brown Bread data).
