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.
