TH1K Class Reference

TH1K class supports the nearest K Neighbours method, widely used in cluster analysis.

This method is especially useful for small statistics. In this method :

  DensityOfProbability ~ 1/DistanceToNearestKthNeighbour
  Ctr TH1K::TH1K(name,title,nbins,xlow,xup,K=0)
  differs from TH1F only by "K"
  K - is the order of K Neighbours method, usually >=3
  K = 0, means default, where K is selected by TH1K in such a way
         that DistanceToNearestKthNeighbour > BinWidth and K >=3

This class has been implemented by Victor Perevoztchikov perev.nosp@m.@bnl.nosp@m..gov
