Figure 1. Coreferentiality coefficients and power of coreferentiality detection with uncorrelated test variables X₁ and X₂.

For each possible combination of various sample sizes and reference data dependency degrees δ (see insert in panel B), 100 data sets were simulated and tested with the permutation test described. Median coreferentiality coefficients R_C. B. Power of detection using the permutation test described (percentage of test p<0.05).
