From: Computing Ka and Ks with a consideration of unequal transitional substitutions
Percentage errors of estimated Ks by YN and MYN when κ Y = 3.75, considering κ R varying from 1 to 10. The percentage error was calculated by the formula 100% × [(estimated value) - (expected value)]/(expected value). Sequences with 2 million codons were simulated with human codon frequencies. Three representative values of ω (0.3 in A, 1 in B, and 3 in C) were used for purifying selection, neutral mutation, and positive selection, respectively.
