R
Although the above presented method is computationally intensive, at present it
causes no problems in most of the standard applications. However, corrections for
multiple comparisons imply very low effective critical values of probabilities needed
to reject the null hypothesis. For the analysis presented in [Durka et al., 2004] critical
values of the order of 10

were routinely obtained. If we set p = 10

in (4.32), we
obtain a minimum N

resampling repetitions to achieve 10% relative error
for the values p(i, j).
