Class MeanResultSet

java.lang.Object
  de.jstacs.results.ResultSet
      de.jstacs.results.NumericalResultSet
          de.jstacs.results.MeanResultSet

All Implemented Interfaces:

Storable

public class MeanResultSet
extends NumericalResultSet

Class that computes the mean and the standard error of a series of NumericalResultSets. Each NumericalResultSet in the series must be added using the method addResults(NumericalResultSet...). The means and the standard errors can be obtained by getStatistics() .

Author:

Jan Grau, Jens Keilwagen

Nested Class Summary

static class	MeanResultSet.AdditionImpossibleException Class for the exception that is thrown if two MeanResultSets should be added that do not match.
static class	MeanResultSet.InconsistentResultNumberException Class for the exception that is thrown if a NumericalResultSet is added to the MeanResultSet that has a number of results which is not equal to the number of results of the previously added results.

Constructor Detail

MeanResultSet

public MeanResultSet(SimpleResult... infos)

Constructs a new MeanResultSet with an empty set of NumericalResultSets.

Parameters:

infos - some information to this MeanResultSet

MeanResultSet

public MeanResultSet()

Constructs a new MeanResultSet with an empty set of NumericalResultSets and no further information.

MeanResultSet

public MeanResultSet(StringBuffer representation)
              throws NonParsableException

The standard constructor for the interface Storable. Creates a new MeanResultSet from the corresponding XML representation.

Parameters:

representation - the XML representation as StringBuffer

Throws:

NonParsableException - if the StringBuffer representation could not be parsed

Method Detail

toXML

public StringBuffer toXML()

Description copied from interface: Storable

This method returns an XML representation as StringBuffer of an instance of the implementing class.

Specified by:

toXML in interface Storable

Overrides:

toXML in class ResultSet

Returns:

the XML representation

fromXML

protected void fromXML(StringBuffer representation)
                throws NonParsableException

Description copied from class: ResultSet

Parses the contents of a ResultSet from its XML representation as returned by ResultSet.toXML().

Overrides:

fromXML in class ResultSet

Parameters:

representation - the XML representation as StringBuffer

Throws:

NonParsableException - if the XML code could not be parsed

addResults

public static MeanResultSet addResults(MeanResultSet r1,
                                       MeanResultSet r2)
                                throws MeanResultSet.AdditionImpossibleException

Adds two MeanResultSets together.

Parameters:

r1 - one MeanResultSet

r2 - another MeanResultSet

Returns:

the merged MeanResultSet

Throws:

MeanResultSet.AdditionImpossibleException - if the Results does not match

addResults

public void addResults(NumericalResultSet... rs)
                throws MeanResultSet.InconsistentResultNumberException,
                       SimpleParameter.IllegalValueException,
                       MeanResultSet.AdditionImpossibleException

Adds NumericalResultSets to this MeanResultSet. The NumericalResultSets are handled as one result. So if you call this method with e.g. three arguments this is the same as adding one combing argument and not the same as calling the method three times, each time with one argument.

Parameters:

rs - the NumericalResultSets to be added

Throws:

MeanResultSet.InconsistentResultNumberException - if the number of results differ

SimpleParameter.IllegalValueException - if the new (merged) value could not be set

MeanResultSet.AdditionImpossibleException - if some results are not comparable (name, comment, type)

getStatistics

public NumericalResultSet getStatistics()

Returns the means and (if possible the) standard errors of the results in this MeanResultSet as a new NumericalResultSet.

Returns:

the means and (if possible the) standard errors of the results in this MeanResultSet

getInfos

public ResultSet getInfos()

Returns some information for this MeanResultSet.

Returns:

the information for this MeanResultSet
