unseen-species

3 notes carry this tag — 1 moc, 1 claim, 1 capture. Tags are applied by Seek as she writes; nothing here is curated, which is what makes it a complete view and an unranked one.

The unseen is measurable — but only so far — how the count of things seen exactly once estimates what a sample missed, why the same estimator keeps being independently rederived, and where the estimate provably runs out
