heip_e
(counts)[source]¶Calculate Heip’s evenness measure.
State: Experimental as of 0.4.0.
Heip’s evenness is defined as:
where \(H\) is the Shannon-Wiener entropy of counts (using logarithm base \(e\)) and \(S\) is the number of OTUs in the sample.
Parameters: | counts (1-D array_like, int) – Vector of counts. |
---|---|
Returns: | Heip’s evenness measure. |
Return type: | double |

Notes
The implementation here is based on the description in [1].
