SECTION 15.19 COCHRAN Q-TEST

The Cochran Q test tests whether three or more sets of matched frequencies differ significantly. The data are assumed to be 0-1 responses by N individuals under K conditions. See S. Siegel and N. J. Castellan, Nonparametric Statistics, 2nd ed., 1988, pp. 170-174.

Be sure to CALL DFLT before calling COCHRANQ and to include the COMMON/BPRINT/ common block. The call is

        CALL COCHRANQ(JRESP,N,K,Q)

where

        JRESP = INTEGER array dimensioned JRESP(N,K) containing
                the responses (input)
        N     = the number of individuals (input)
        K     = the number of conditions (input)
        Q     = single precision real variable containing
	        the calculated Chi Squared value (output)
