Member Function Documentation

getBinIndices()

std::vector< int > getBinIndices ( const std::vector< float >  values )

inlineprivate

Maps the vector of input values to their bin index in N dimensions.

If the values lie outside the covered region -1 is returned.

Parameters

values

N dimensional vector of values to be mapped to a global linear bin index.

Definition at line 91 of file ECLChargedPIDMVAWeights.h.

    {
      std::vector<int> binIndices(m_binEdges.size());
 
      for (unsigned int i = 0; i < m_binEdges.size(); i++) {
        std::vector<float> dimBinEdges = m_binEdges[i];
        auto it = std::upper_bound(dimBinEdges.begin(), dimBinEdges.end(), values[i]);
        if (it == dimBinEdges.end()) {
          binIndices[i] = -1;
        } else {
          int index = std::distance(dimBinEdges.begin(), it) - 1;
          binIndices[i] = index;
        }
      }
      return binIndices;
    }

getLinearisedBinIndex()

int getLinearisedBinIndex ( const std::vector< float >  values )

inline

Maps the vector of input values to a global bin index.

If any of the values lies outside the binning -1 is returned.

Parameters

values

N dimensional vector of values to be mapped to a global linear bin index.

Definition at line 69 of file ECLChargedPIDMVAWeights.h.

    {
      int globalBin(-1);
      std::vector<int> binIndices = getBinIndices(values);
      for (unsigned int i = 0; i < binIndices.size(); i++) {
        if (binIndices[i] < 0) return -1;
        if (i == 0) {
          globalBin = binIndices[i];
        } else {
          globalBin = globalBin * m_nBins[i] + binIndices[i];
