Notes
The implementation here is based on the equations in the EstimateS manual [1]. Different equations are employed to calculate the chao1 variance and confidence interval depending on bias_corrected and the presence/absence of singletons and/or doubletons.
Specifically, the following EstimateS equations are used:
bias_corrected=True
, Equations 6, 13.bias_corrected=False
, Equations 5, 13.References
