class TMVA::PDEFoamMultiTarget: public TMVA::PDEFoamEvent


 PDEFoamMultiTarget

 This PDEFoam variant is used to estimate multiple targets by
 creating an event density foam (PDEFoamEvent), which has dimension:

    dimension = number of variables + number targets

 This PDEFoam variant stores in every cell the sum of event weights
 and the sum of the squared event weights.  During evaluation for a
 given event, which has only variables and no targets (number of
 event variables is smaller than the foam dimension), the targets
 are estimated by finding all cells, which correspond to this event
 and calculate the Mean (or Mpv, depending on the ETargetSelection)
 cell center weighted by the event density in the cell.

 This PDEFoam variant should be booked together with the
 PDEFoamEventDensity density estimator, which returns the event
 weight density at a given phase space point during the foam
 build-up.

Function documentation

PDEFoamMultiTarget()
 Default constructor for streamer, user should not use it.
PDEFoamMultiTarget(const TString& , TMVA::ETargetSelection )
 User constructor

 Parameters:

 - name - name of PDEFoam object

 - ts - target selection method used in
   GetCellValue(const std::map<Int_t, Float_t>& xvec, ECellValue)
   Cadidates are: TMVA::kMean, TMVA::kMpv

   - TMVA::kMean - The function GetCellValue() finds all cells
     which contain a given event vector 'xvec' and returns the
     mean target (for every target variable in the foam).

   - TMVA::kMpv - The function GetCellValue() finds all cells
     which contain a given event vector 'xvec' and returns the
     most probable target (for every target variable in the
     foam), that is the target value which corresponds to the
     cell with the largest event density.
PDEFoamMultiTarget(const TMVA::PDEFoamMultiTarget& )
 Copy Constructor  NOT IMPLEMENTED (NEVER USED)
std::vector<Float_t> GetCellValue(const map<Int_t,Float_t>& , TMVA::ECellValue )
 This function is overridden from PDFEFoam.  It returns all
 regression targets (in order), given an untransformed event
 vector 'xvec'.  The key of 'xvec' is the dimension and the value
 (Float_t) is the coordinate.

 Note: number of foam dimensions = number of variables + number
 of targets

 Parameters:
 - xvec - map of event variables (no targets!)
 - cv - cell value to return (ignored!)

 Return:
 Targets, ordered by missing dimensions in 'xvec'.
 The size of the returned vector = foam dimension - size of xvec.
void CalculateMpv(map<Int_t,Float_t>& , const vector<TMVA::PDEFoamCell*>& )
 This function calculates the most probable target value from a
 given number of cells.  The most probable target is defined to
 be the coordinates of the cell which has the biggest event
 density.

 Parameters:

 - target - map of targets, where the key is the dimension and
   the value is the target value.  It is assumed that this map is
   initialized such that there is a map entry for every target.

 - cells - vector of PDEFoam cells to pick the most probable
   target from
void CalculateMean(map<Int_t,Float_t>& , const vector<TMVA::PDEFoamCell*>& )
 This function calculates the mean target value from a given
 number of cells.  As weight the event density of the cell is
 used.

 Parameters:

 - target - map of targets, where the key is the dimension and
   the value is the target value.  It is assumed that this map is
   initialized such that there is a map entry for every target
   with all target values set to zero.

 - cells - vector of PDEFoam cells to pick the most probable
   target from
