class TH1K: public TH1, public TArrayF

 The TH1K Class

  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@bnl.gov>

Function documentation

TH1K()
 Constructor.
TH1K(const char* name, const char* title, Int_t nbinsx, Double_t xlow, Double_t xup, Int_t k = 0)
 Create a 1-Dim histogram with fix bins of type float
 (see TH1K::TH1 for explanation of parameters)
~TH1K()
 Destructor.
void Copy(TObject& obj) const
 Copy this histogram structure to newth1.

 Note that this function does not copy the list of associated functions.
 Use TObject::Clone to make a full copy of an histogram.
Int_t Fill(Double_t x)
 Increment bin with abscissa X by 1.

 if x is less than the low-edge of the first bin, the Underflow bin is incremented
 if x is greater than the upper edge of last bin, the Overflow bin is incremented

 If the storage of the sum of squares of weights has been triggered,
 via the function Sumw2, then the sum of the squares of weights is incremented
 by 1 in the bin corresponding to x.
Double_t GetBinContent(Int_t bin) const
 Return content of global bin number bin.
Double_t GetBinError(Int_t bin) const
 Return content of global bin error.
void Reset(Option_t* option = "")
 Reset.
void SavePrimitive(ostream& out, Option_t* option = "")
 Save primitive as a C++ statement(s) on output stream out
 Note the following restrictions in the code generated:
  - variable bin size not implemented
  - Objects in list of functions not saved (fits)
  - Contours not saved
void Sort()
 Sort.

Double_t GetBinContent(Int_t bin, Int_t ) const
{return GetBinContent(bin);}
Double_t GetBinError(Int_t bin) const
Double_t GetBinError(Int_t bin, Int_t ) const
