Stroke Patient Data

Description

This dataset, analyzed by Bishop and Fienberg (1969) and Bishop, Fienberg and Holland (1975, Section 5.2), describes 121 patients treated for stroke at Massachusetts General Hospital. Each patient's symptoms of physical disability were graded on a five-point scale upon admission and again upon discharge. Because patients were not released if their symptoms got worse, the second score is always equal to or better than the first score, and cells in the two-way table above the diagonal may be regarded as structural zeros.
