Calculates the curvature of the rarefaction curve of the full observed data.
Usage
Curvature(dss)
Arguments
dss
list of objects of class divsubsamples.
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.
Value
numeric, between 0 and 1
