## Detailed Description

The basic counter used for Monitoring purposes.

It is used as a small helper class for implementation of class ChronoStatSvc but it also could be used in stand-alone mode to perform trivial statistical evaluations. e.g.

Essentially the generic counter could be considered as the trivial 1-bin

// get all tracks
const Tracks* tracks = ... ;
// create the counter
StatEntity chi2 ;
// make a loop over all tracks:
for ( Tracks::const_iterator itrack = tracks->begin() ;
tracks->end() != itrack ; ++itrack )
{
const Track* track = *itrack ;
// use the counters to accumulate information:
chi2 += track -> chi2 () ;
} ;
// Extract the information from the counter:
// get number of entries (== number of tracks)
int nEntries = chi2.nEntries() ;
// get the minimal value of chi2
double chi2Min = chi2.flagMin() ;
// get the average value of chi2:
double meanChi2 = chi2.flagMean() ;
// get R.M.S. for chi2-distribution:
double rmsChi2 = chi2.flagRMS() ;
.. etc...

double StatEntity::efficiency | ( |  | ) | const
| inline

Interpret the counter as some measure of efficiency The efficiency is calculated as the ratio of the weight over the number of entries One gets the correct interpretation in the case of filling the counters only with 0 and 1.

Some checks are performed:

- number of counts must be positive
- "flag" must be non-negative
- "flag" does not exceed the overall number of counts

If these conditions are not satisfied the method returns -1, otherwise it returns the value of "flagMean"

StatEntity& stat = ... ;
for ( TRACKS::iterator itrack = tracks.begin() ;
tracks.end() != itrack ; itrack )
{
const bool good = PT( *itrack ) > 1 * Gaudi::Units::GeV ;
stat += good ;
}
std::cout << " Efficiency of PT-cut is "
<< stat.efficiency() << std::endl ;

double StatEntity::efficiencyErr | ( |  | ) | const
| inline

Interpret the counter as some measure of efficiency and evaluate the uncertainty of this efficiency using binomial estimate.

The efficiency is calculated as the ratio of the weight over the number of entries One gets the correct interpretation in the case of filling the counters only with 0 and 1. Some checks are performed:

- number of counts must be positive
- "flag" must be non-negative
- "flag" does not exceed the overall number of counts

If these conditions are not satisfied the method returns -1.

Attention
  The action of this method is DIFFERENT from the action of the method StatEntity::flagMeanErr

StatEntity& stat = ... ;
for ( TRACKS::iterator itrack = tracks.begin() ;
tracks.end() != itrack ; itrack )
{
const bool good = PT( *itrack ) > 1 * Gaudi::Units::GeV ;
stat += good ;
}
