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.
