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.

qpl1 |
lower equivalence limit q_+^{\prime} to the target functional q_+ |
qpl2 |
upper equivalence limit q_+^{\prime\prime} to the target functional q_+ |

row vector with the intraindividual differences for all n pairs as components |
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].
