Statistical tests in experimental psychiatric research.
It is pointed out that the subjects used in psychiatric research experiments are usually drawn in such a way as to invalidate many of the commonly applied statistical tests. The necessarily non-statistical component of any inference is noted, and the area where one might hope for an exact statistical inference is identified. A class of tests permitting such inferences is described. Their theoretical and practical advantages are outlined.
