Description
One approach to biodiversity measurement is fitting a distribution to species abundance data. In the present case data on abundance of different species is recorded at two Indian localities in western-ghats (Arvind and Dhoni). These data are said to be 'Frequency of frequency'.
Some ecological considerations suggest that a log-normal distribution should fit the data. S - the number of species observed and area under the curve to the left of 1/2 are used together to estimate the number of 'unseen' species.
Usage
1
Format
A data frame with 305 observations on the following 3 variables.
SiteThe sites
AbundanceThe number of species with abundance r each
SpeciesThe numberof individual birds sighted
Details
Report your findings with fitting log-normal distribution and Chi-square test for Goodness of fit.
