Constructor Detail

PMMExplainingAwayResidual

public PMMExplainingAwayResidual(StringBuffer buf)
                          throws NonParsableException

The standard constructor for the interface Storable. Recreates a PMMExplainingAwayResidual from its XML representation as returned by Measure.toXML().

Parameters:

buf - the XML representation as StringBuffer

Throws:

NonParsableException - if the XML code could not be parsed

PMMExplainingAwayResidual

public PMMExplainingAwayResidual(byte order,
                                 double[] ess)
                          throws Exception

Creates a new PMMExplainingAwayResidual of order order.

Parameters:

order - the order, may be 1 or 2

ess - the equivalent sample sizes of both classes

Throws:

Exception - if the order is not 1 or 2

PMMExplainingAwayResidual

public PMMExplainingAwayResidual(PMMExplainingAwayResidual.PMMExplainingAwayResidualParameterSet parameters)
                          throws Exception

Creates a new PMMExplainingAwayResidual from the corresponding InstanceParameterSet parameters/code>.

Parameters:

parameters - the corresponding parameters

Throws:

Exception - if the order is not 1 or 2

Method Detail

getInstanceName

public String getInstanceName()

Description copied from class: Measure

Returns the name of the Measure and possibly some additional information about the current instance.

Specified by:

getInstanceName in class Measure

Returns:

the name of the Measure

getParents

public int[][] getParents(DataSet fg,
                          DataSet bg,
                          double[] weightsFg,
                          double[] weightsBg,
                          int length)
                   throws Exception

Description copied from class: Measure

Returns the optimal parents for the given data and weights. The returned array of parents p at each position i is build as follows:

• p[i][p.length - 1] contains the index i itself
• p[i][p.length - 2] contains the "most important" parent
• ...
• p[i][0] contains the "least important" parent

Specified by:

getParents in class Measure

Parameters:

fg - the data of the current (foreground) class

bg - the data of the negative (background) class

weightsFg - the weights for the sequences of fg

weightsBg - the weights for the sequences of bg

length - the length of the model, must be equal to the length of the sequences

Returns:

the the array p with the optimal parents

Throws:

Exception - if the lengths do not match or other problems concerning the data occur

getXMLTag

public String getXMLTag()

Description copied from class: Measure

Returns the XML-tag for storing this measure

Specified by:

getXMLTag in class Measure

Returns:

the tag
