The fit of the regression models was evaluated by the explained variance of the model and by a permutation test based on a Generalized Goodall's F-Test with 10,000 permutations.
The P-value is calculated by a permutation test as mentioned above, with the difference of randomly permuting the labels within each population independently, and using the statistic CCPmax instead of CCmax.
Additionally, each ROC curve was assessed by a permutation test.
The threshold LOD value was determined by a permutation test involving 3000 runs at a significance level of p = 0.05.
The CCA yielded correlations that were validated by a permutation test between species composition and canopy openness, nitrogen content, pH, base saturation and soil aluminum content.
Wind power classes with the same letter are not significantly different by a permutation test (p > 0.001); the comparisons are made within land use category and species.
The significance of the weighted degree values was evaluated by a permutation test, with the number of drug trials kept constant.
FST was estimated per genomic windows of 500 Kb and the significance of FST values was estimated by a permutation test (1000 permutations per population pair).
RK-gag was 70% higher than the codon optimized AD-gag, with a p-value <0.00001 calculated by a permutation test (see Figure 1).
The top-ranked interaction model was chosen for a given order of interaction, and its P value of prediction accuracy (PA) was evaluated by a permutation test based on 1000 shuffles of the adjusted phenotypic values.
The significance of STEM profiles are calculated by comparing the number of proteins assigned the number of proteins expected by a permutation test (50 being the default value) and the profiles p-value.
