Table 5.

Symmetric difference values between true tree and neighbor-joining trees constructed from k-tuple distance based on three different distances metrics^a

Distance metrics	LPS9 (from global binary table)	LPS9 (from global frequency table)	5-tuple (from global binary table)	5-tuple (from global frequency table)
dLog	10	10	18	18
dPear	14	6	18	26
dk	14	8	18	26

^aNote: We measured the accuracy of the LifePrint set of 9-tuples (LPS9) and complete set of 5-tuple methods by comparing each neighbor-joining tree with the true tree using a symmetric difference.

Abbreviations: dLog, k-tuple distance based on the Jaccard index; dPear, k-tuple distance based on the Pearson’s correlation coefficient; dk, typical k-tuple distance.
