The longitudinal ordinal data analysed in the worked example of Munzel and Brunner
(2002, Table 2). The patient rated global impression (PGI) was recorded for 15 patients
with panic disorder at baseline and after 4 weeks of a physical exercise therapy. The
PGI score is ordered categorical. The data illustrate the exact paired rank test
(pairedRankTest): the paper reports \(T_R = -186\), \(D^+ = 29\) and a
two-sided exact p-value of 0.010.
