Published in [Thrun et al, 2016] for the case of automatically estimating the radius of the P-matrix. Can also be used to estimate the radius parameter for distance based clustering algorithms.
EstimateRadiusByDistance(DistanceMatrix)
Arguments
DistanceMatrix: [1:n,1:n] symmetric distance Matrix of n cases
Details
For density-based clustering algorithms like DBSCAN it is not always usefull.
Returns
Numerical scalar defining the radius
