Figure 1From: Statistical tests to identify appropriate types of nucleotide sequence recoding in molecular phylogeneticsPP -plot for the three tests with respect to S ′ = R , Y . The observed P-values were calculated from 5000 Monte Carlo experiments for each test (i.e., the Index test (a), the Markov chain test (b), and the likelihood-ratio test (c)) and charted against the expected P-values.Back to article page
