## Pork Tasting Data

### Description

Bradley and Terry (1952) provide the individual choice matrices 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.

### Usage

`data(pork)`

### Format

A 3d array consisting of ten square matrices. The first five matrices
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.
