of two judges choosing between pairs of three samples
of pork meet. The pigs had been fed on either corn
(C), corn plus peanut supplement (Cp), or corn plus a
large peanut supplement (CP). Each judge does five
repetitions. The data are stored in a 3d array, the
first five matrices of which correspond to the five
repetitions of the first judge, the last five to the
repetitions of the second judge. Row stimuli are
chosen (preferred) over column stimuli.
