TUnfoldBinning Class Reference

This class serves as a container of analysis bins analysis bins are specified by defining the axes of a distribution.

TUnfold is used to decompose a measurement y into several sources x given the measurement uncertainties and a matrix of migrations A.

It is also possible to have unconnected analysis bins without axis. Multiple TUnfoldBinning objects may be arranged in a tree, such that a full tree structure of histograms and bins is supported

If you use this software, please consider the following citation S.Schmitt, JINST 7 (2012) T10003 [arXiv:1205.6201]

More documentation and updates are available on http://www.desy.de/~sschmitt

Functionality

The class gives access to all analysis bins numbered in sequence. Such a sequence of bins may be stored in a 1-dimension histogram. Correlations between two TUnfoldBinning objects may be stored in a 2-dimensional histogram. This type of ordering is required for the TUnfold class.

In addition, it is possible to have root histograms, using the axes as defined with the distributions. Underflow/overflow bins can be included or excluded when mapping bins on root histograms. In addition, it is possible to collapse one of more axes when going from a N-dimensional distribution to a root histogram.

More details are described with the documentation of TUnfold.

For most applications, it is best to use TUnfoldDensity instead of using TUnfoldSys or TUnfold

As compared to TUnfold, TUndolfDensity adds the following functionality background subtraction (see documentation of TUnfoldSys) error propagation (see documentation of TUnfoldSys) regularisation schemes respecting the bin widths support for complex, multidimensional input distributions

Complex binning schemes are imposed on the measurements y and on the result vector x with the help of the class TUnfoldBinning The components of x or y are part of multi-dimensional distributions. The bin widths along the relevant directions in these distributions are used to calculate bin densities (number of events divided by bin width) or to calculate derivatives taking into account the proper distance of adjacent bin centers

Complex binning schemes

in literature on unfolding, the "standard" test case is a one-dimensional distribution without underflow or overflow bins. The migration matrix is almost diagonal.

This "standard" case is rarely realized for real problems.

Often one has to deal with multi-dimensional input distributions. In addition, there are underflow and overflow bins or other background bins, possibly determined with the help of auxillary measurements

In TUnfoldDensity, such complex binning schemes are handled with the help of the class TUnfoldBinning. For each vector there is a tree structure. The tree nodes hold multi-dimensiopnal distributions

For example, the "measurement" tree could have two leaves, one for the primary distribution and one for auxillary measurements

Similarly, the "truth" tree could have two leaves, one for the signal and one for the background.

each of the leaves may then have a multi-dimensional distribution.

The class TUnfoldBinning takes care to map all bins of the "measurement" to the one-dimensional vector y. Similarly, the "truth" bins are mapped to the vector x.

Choice of the regularisation

In TUnfoldDensity, two methods are implemented to determine tau**2

  1. ScanLcurve() locate the tau where the L-curve plot has a "kink" this function is implemented in the TUnfold class
  2. ScanTau() finds the solution such that some variable (e.g. global correlation coefficient) is minimized this function is implemented in the TUnfoldDensity class, such that the variable could be made depend on the binning scheme

Each of the algorithms has its own advantages and disadvantages

The algorithm (1) does not work if the input data are too similar to the MC prediction, that is unfolding with tau=0 gives a least-square sum of zero. Typical no-go cases of the L-curve scan are:

The algorithm (2) only works if the variable does have a real minimum as a function of tau. If global correlations are minimized, the situation is as follows: The matrix of migration typically introduces negative correlations. The area constraint introduces some positive correlation. Regularisation on the "size" introduces no correlation. Regularisation on 1st or 2nd derivatives adds positive correlations. For this reason, "size" regularisation does not work well with the tau-scan: the higher tau, the smaller rho, but there is no minimum. In contrast, the tau-scan is expected to work well with 1st or 2nd derivative regularisation, because at some point the negative correlations from migrations are approximately cancelled by the positive correlations from the regularisation conditions.

whichever algorithm is used, the output has to be checked:

  1. The L-curve should have approximate L-shape and the final choice of tau should not be at the very edge of the scanned region
  2. The scan result should have a well-defined minimum and the final choice of tau should sit right in the minimum
