Top  Previous  Next

 

A number of models have been proposed to describe the species - abundance relationship, of which the four models available for fitting in Species Diversity and Richness are by far the most important. All four methods use a similar tabbed output window. When any of these buttons is first activated the selected distribution is fitted to the data in sample 1. To selected a different sample for analysis use the drop down menu at the bottom of the window.
