This paper describes research into a new estimate for the number of uniques in a population based on the information provided by an observed sample. That estimate forms the basis of an estimate for the proportion of uniques in the sample which are unique in the population. The estimate is produced by a fitting algorithm, and much of the work so far has been directed toward producing a good fit.The fitting algorithm is described in detail and results are presented for 25 samples from a known population. While the setting is limited, the results are encouraging.
