Understanding Species' Abundance
Abstract: Considered is a multi-species assemblage in an infinite population
with unknown and possibly heterogeneous species' abundance levels. A random
sample of a fixed size (n) has been drawn only to realize a certain
species distribution. At this stage, there are two interesting inference
problems : (i) Prediction of the unknown proportion of the collective abundance
of all hitherto unrealized species; (ii) Assessment of the quantum of additional
units to be sampled [in terms of the sample size n] to realize a certain number
of hitherto unobserved species. Finite population analogue of this problem is also worth discussing.
I propose to review the available literature in this fascinating area of
research.
