    Mol Biol Evol 15:910-7. 1998
    ..Site-to-site differences in rates, as well as synonymous/nonsynonymous and first/second/third-codon-position differences, arise as a natural consequence of the site-to-site differences in amino acid frequencies...

    Department of Molecular Genetics and Microbiology, Health Sciences Center, University of New Mexico, Albuquerque 87131, USA
    Biometrics 55:1044-50. 1999
    ..The test is compared to the Kolmogorov-Smirnov two-sample test, the maximally selected chi-square, and a likelihood ratio test. The tests are applied to assessing recombination in genetic sequences of HIV...
