Similarity index to compare overlap across samples?

[g080]

Good afternoon,

I am trying to use JMP to calculate similarity indices (like Morisita-Horn) for determine overlap/similarity among samples.

I am using this for ecological research -  I have multiple study sites and a list of species that occur in each (including abundance data).  I would like to measure overlap among the sites, taking into account abundance at each.  Can you please help refer me to the right analysis in JMP?

I anticipate there will be a need to transform the data set from a list of species names into something else (every species with its own number?), so any insight into how the dataset should be formatted is also appreciated

Thank you in advance.

I think using EstimateS (free) is the best way.
