Statistical data collection


Detailed Description

OMNeT++ provides a variety of statistical classes.

There are basic classes which compute basic statistics like mean and standard deviation, some classes deal with density estimation, and other classes support automatic detection of the end of a transient, and automatic detection of accuracy of collected statistics.

The two main abstract base classes are cStatistic and cDensityEstBase. Most other classes are mostly polymorphic on these two, which means most functionality in subclasses is available via virtual functions defined in cStatistic and cDensityEstBase. The transient detection and result accuracy classes are derived from the cTransientDetection and cAccuracyDetection abstract base classes.

The classes are:

Transient and result accuracy detection classes:

Some other classes closely related to the above ones are not listed here explicitly, but you can find them via 'See also' links from their main classes.
