Throughout the paper it was written that the test E_OUV gives a measure of how GC content varies within genomes. This is not accurate, since the formula (E_OUV) is concerned with all nucleotides (A, G, C, and T). A more fitting description is "Variation of base composition within genomes." Thus, the equation: YE_OUV=exp(-10.7-16.7XGC+14.3X2GC), actually describes how base composition, measured as varying 4-tuples of mononucleotide frequencies, varies within genomes.
