Top  Previous  Next


After a diversity index method has been run, a standard bootstrap method for estimating upper and lower 95% confidence intervals can be undertaken. In the output window holding the estimated diversity index for each sample, first select a sample by clicking on its title. The selected row turns blue and a symbol indicates that you have selected the row (image below). Then select the bootstrap button at the top of the window.


Alternatively, use the Bootstrap All button to calculate the confidence intervals for all samples. Bootstrap confidence intervals are not automatically calculated because with large data sets they can take a long time to calculate.
