The measurement of size diversity

This webpage provides a free program for measuring the size diversity of a size distribution. The program "diversity08" was programmed by J.J. Egozcue, February 2008, following the methods presented in Quintana et al. (2008) Limnology and Oceanography: Methods, 6:75-86. It is based on a non-parametric kernel estimation, after data standardization by division of sample geometric mean. This method is applicable to any type of size distribution, even if it doesn’t fit a parametric function, and allows its immediate comparison with the size diversity of other distributions independently of the method used for size estimation. See the above reference for more details on the method.
