- Title
Approximate bias of the estimated proportion in group testing.
- Authors
Hepworth, Graham
- Abstract
The maximum likelihood estimator for estimating proportions by group testing is biased. An expression for the approximate bias has been previously presented, which enables the creation of a less biased estimator by removing the term of $$O(n^{-1})$$ . However, in this previous work the term of $$O(n^{-2})$$ was incorrectly derived. This note gives a correct derivation, and examines the relative contribution of the two terms.
