n, number of sequences; S_nuc, number of variable nucleotide sites; S_aa, number of variable amino acid sites; S_syn, number of variable synonymous nucleotide sites; K_nuc, mean number of pairwise differences between nucleotide sequences; K_aa, mean number of pairwise differences between amino acid sequences; K_syn, mean number of pairwise differences at synonymous nucleotide sites; D_nuc, value of the test statistic for goodness-of-fit to a neutral model (20) (nucleotide sequences); D_aa, value of the test statistic for goodness-of-fit to a neutral model (amino acid sequences); D_syn, value of the test statistic for goodness-of-fit to a neutral model (20) (synonymous nucleotide sites).
