Implementation of the paired-data analogue of the Mann-Whitney-Wilcoxon test for
equivalence of continuous distributions. The continuity assumption relates to the
intraindividual differences *D_i*. For details see Wellek S (2010) Testing statistical
hypotheses of equivalence and noninferiority. Second edition,*Par.* 5.4.

*q_+* is the probability of getting a positive sign of the so-called Walsh-average
of a pair of within-subject differences and can be viewed as a natural paired-observations
analogue of the Mann-Whitney functional *π_+ = P[X>Y]*.
