Gower

\[D_{Gower} = \sum_{j=1}^{S_T} \frac {|S_{Aj} - S_{Bj} |} {(\max S_{ij} - \min S_{ij})}\]

• where \(S_{Aj}\) is the abundance of sample A in the jth OTU.
• where \(S_{Bj}\) is the abundance of sample B in the jth OTU.
• where \(\max S_{ij}\) is the maximum abundance in the jth OTU over all samples.
• where \(\min S_A{ij}\) is the minimum abundance in the jth OTU over all samples.
