Diversity.
Comparing diversity under collection bias.
An interactive companion to our Royal Society Interface paper on collection bias: set up two assemblages, bias how their records were collected, and see which standardization strategy still recovers the true diversity ratio.
What Shall We Do with the Unseen Sailor?.
Applies unseen species models to VOC historical records to estimate the true number of sailors missing from the archive.
Population Size Estimation as a Regression Problem.
Reframes population size estimation as a Bayesian regression problem to correct for heterogeneous detection probabilities in cultural samples.
Demystifying Chao1 with Good-Turing.
How Good-Turing frequency estimation underpins the Chao1 biodiversity estimator — and what that means for counting unseen cultural artefacts.
