d1, unweighted average distance; d2, average distance weighted with sequence length; d3, multiprotein gamma distance; dL, Lynch's distance. The standard errors for the CD approach were computed by the jackknife method. The standard errors of t̂1 and t̂2 obtained by using Eq. 5 for d3 with a = 0.57 were 2.0 and 4.0, respectively.
