Description
Interface Summary  

ArrayOfObservationListener  Represents an object that can listen to observations broadcast by lists of statistical probes. 
Class Summary  

ListOfStatProbes<E extends StatProbe>  Represents a list of statistical probes that can be managed simultaneously. 
ListOfTallies<E extends Tally>  Represents a list of tally statistical collectors. 
ListOfTalliesWithCovariance<E extends Tally>  Extends ListOfTallies to add support for the computation
of the sample covariance between each pair of elements
in a list, without storing all observations. 
Provides support for lists of statistical probes. Sometimes, a simulator computes several related performance measures such as the quality of service for different call types in a phone call center, the waiting times of different types of customers, the average number of pieces of different types a machine processes, etc. A list of statistical probes, in contrast with an ordinary array, can be resized. Since a list of statistical probes implements the Java List interface, one can iterate over each probe, e.g., to set reporting options. In addition to an ordinary list, a list of probes provides facilities to get a vector of averages, a vector of sums, and to create reports.
In the Java programming language, a list is usually constructed empty, and filled with items. Lists of statistical probes can be constructed this generic way, or created using factory methods that automatically construct the probes.
ListOfStatProbes
is
the base class for
lists of statistical probes. It can hold a list of any
StatProbe
subclass, and
provides the basic
facilities to obtain an array of sums, an array of averages, etc.
Subclasses provide probespecific functionalities for adding
vectors of observations, computing sample covariances, etc.
ListOfTallies
is
used to contain Tally
instances.
A subclass,
ListOfTalliesWithCovariance
, is
provided to add support for covariance computation without storing observations.
All classes in this package representing lists of probes support the
observer design pattern
similarly to the classes in package stat.
A list of statistical probes maintains a list of registered
ArrayOfObservationListener
objects, and broadcasts information to all its registered
observers when it receives a new vector of observations.
Any object that implements the interface
ArrayOfObservationListener
can register as an observer.
