Geometricbirds


4. One approach to biodiversity measurement is fitting a distribution to rank abundance data. In the present case data on abundance of different species is recorded at two localities in western-ghats in India. The species are ranked from most abundant (rank 1) to least abundant. Some ecological considerations suggest that a geometric distribution should fit the data. Parameter of the geometric distribution is taken as indicator of diversity. Higher the value of parameter, lower the diversity.


datasets

Collection of datasets as prepared by Profs. A.P. Gore, S.A. Paranjape, and M.B. Kulkarni of Department of Statistics, Poona University, India. With their permission, first letter of their names forms the name of this package, the package has been built by me and made available for the benefit of R users. This collection requires a rich class of models and can be a very useful building block for a beginner.
