brillouin_d
(counts)[source]¶Calculate Brillouin index of alpha diversity.
State: Experimental as of 0.4.0.
This is calculated as follows:
where \(N\) is defined as the total number of individuals in the sample, \(s\) is the number of OTUs, and \(n_i\) is defined as the number of individuals in the \(i^{\text{th}}\) OTU.
counts (1-D array_like, int) – Vector of counts.
Brillouin index.
double
Notes
The implementation here is based on the description given in the SDR-IV online manual 1.
