Calculates the curvature of the rarefaction curve of the full observed data.
Usage
Curvature(dss)
Arguments
dss
list of objects of class DivSubsamples.
Value
numeric, between 0 and 1
Details
Curvature calculates the curvature of the full observed data. If dss contains more than one subsample (i.e. if length(dss)>1), the curvature of the largest subsample is calculated. If the curvature value is \(< 0.1\), researchers should exercise caution as this is indicative of severe under-sampling, in which case DivE is prone to error.
