Diversity Index (for VNTR data): a measure of the variation of the number of repeats at each locus. It ranges from 0.0 (no diversity) to 1.0 (complete diversity).

Confidence Interval: precision of the Diversity Index, expressed as 95% upper and lower boundaries.

max (pi): fraction of samples that have the most frequent repeat number in this locus (range 0.0–1.0).
