Figure 5. R_C and power of coreferentiality detection with correlated test variables, and reference variables dependent on either one or both.

For indicated dependency degrees δ, sample sizes N and correlations R between the test variables, 100 data sets were simulated respectively and tested with the permutation test described (lines with closed symbols according to the insert in panel A). The same was then repeated in the condition that reference data depended on only one test variable (lines with open symbols). A. Median coreferentiality coefficients R_C. B. Power of detection using the permutation test described (percentage of test p<0.05).
