Description
Chakrapani and Ehrenberg [1981] analyzed people's attitudes towards a
variety of breakfast cereals. The data matrix cereal is 8 ? 11, with rows
corresponding to eight cereals, and columns corresponding to potential
attributes about cereals. The original data consisted of the percentage of
subjects who thought the given cereal possessed the given attribute. The
present matrix has been doubly centered, so that the row means and columns
means are all zero. (The original data can be found in the S-Plus [TIBCO
Software Inc., 2009] data set cereal.attitude.)
