Sigma(NucleicAcid, NucleicAcid)
A measure of difference between two sequences f and g (from different organisms or from different regions of the same genome) is the average absolute dinucleotide relative abundance difference calculated as
sigma(f, g) = (1/16)*∑|pXY(f)-pXY(g)|where the sum extends over all dinucleotides (abbreviated sigma-differences).
