**Example Calculations**

***.sharedJest**

<math>S_{sharedJest} = \frac{S_{sharedChao1}}{S1_{chao} + S2_{chao} - S_{sharedChao1}}</math>,

where,

Ssharedchao1 = estimated number of OTUs shared between A and B using the SharedChao1 estimator. S1chao = number of OTUs estimated in A using the Chao estimator. S2chao = number of OTUs estimated in B using the Chao estimator.

For this example the value was 0.88.
