Estimating Diversity via Frequency Ratios [PDF]
Biometrics, 2015 SummaryWe wish to estimate the total number of classes in a population based on sample counts, especially in the presence of high latent diversity. Drawing on probability theory that characterizes distributions on the integers by ratios of consecutive probabilities, we construct a nonlinear regression model for the ratios of consecutive frequency ...
