Elusion & Recall

Estimate elusion rate, remaining responsive material, and recall bounds from an elusion sample.

Elusion rate = responsive in elusion sample / elusion sample size; recall = responsive found / (responsive found + estimated remaining responsive).

Use after ranking or review to estimate what may remain in the unreviewed or discarded population.
