Example Calculations

*boot*

These files give the bootstrap estimate as described by Smith and Van Belle (5) but implemented for a single "quadrant".


<math>S_{Bootstrap} = S_{obs} + \sum_{i=1}^{S_{obs}} \left ( 1 - \frac {S_i}{N}\right )^N </math>

where,

N = The number of individuals sampled

<math>S_{i}</math> = The number of sequences in the ith OTU


For the Amazonian dataset SBootstrap=112.33 and there is not a simple expression for the 95% confidence interval.
