    • General time reversible distances with unequal rates across sites 

      Waddell, Peter J.; Steel, M. A. (University of Canterbury. Dept. of Mathematics, 1996)
      A series of new results, with proofs, useful to the study of DNA sequences using Markov models of substitution are presented. General time-reversible distances can be extended to accommodate any fixed distribution of ...
    • Improved analyses of human mtDNA sequence support a recent African origin for Homo sapiens 

      Penny, David; Steel, Mike; Waddell, Peter J.; Hendy, Michael D. (University of Canterbury. Dept. of Mathematics, 1995)
      New quantitative methods including several new techniques are reported for the 135 human mitochondrial sequences from Vigilant et al. (1991 ). General problems in analyzing large numbers of short sequences are discussed ...
    • Rapid evaluation of least squares and minimum evolution criteria on phylogenetic trees 

      Bryant, David James; Waddell, Peter J. (University of Canterbury. Dept. of Mathematics, 1997)
      We present fast new algorithms for evaluating trees with respect to least squares and minimum evolution (ME), the most commonly used criteria for inferring phylogenetic trees from distance data. These include: an ...
