fileToInstances

public static java.util.List<Instance> fileToInstances(java.lang.String path)

fileToMatrix

public static java.util.List<java.util.List<java.lang.Double>> fileToMatrix(java.lang.String path)

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Throws:

java.lang.Exception

getDescription

public void getDescription(java.lang.StringBuilder sb,
                           int indent)

Description copied from interface: MOAObject

Returns a string representation of this object. Used in AbstractMOAObject.toString to give a string representation of the object.

Specified by:

getDescription in interface MOAObject

Parameters:

sb - the stringbuilder to add the description

indent - the number of characters to indent

test

public double test(java.util.List<Instance> x,
                   java.util.List<Instance> y)

Description copied from interface: StatisticalTest

This method performs a test and returns the correspoding p-value.

Specified by:

test in interface StatisticalTest

Parameters:

x - List of instances

y - List of instances

Returns:

p-value

prepareForUseImpl

protected void prepareForUseImpl(TaskMonitor monitor,
                                 ObjectRepository repository)

Description copied from class: AbstractOptionHandler

This method describes the implementation of how to prepare this object for use. All classes that extends this class have to implement prepareForUseImpl and not prepareForUse since prepareForUse calls prepareForUseImpl.

Specified by:

prepareForUseImpl in class AbstractOptionHandler

Parameters:

monitor - the TaskMonitor to use

repository - the ObjectRepository to use

call

public java.lang.Double call()
                      throws java.lang.Exception

Specified by:

call in interface java.util.concurrent.Callable<java.lang.Double>

Throws:

java.lang.Exception

set

public void set(java.util.List<Instance> x,
                java.util.List<Instance> y)

Description copied from interface: StatisticalTest

This method sets the instances for later use in concurrent scenarios. The test is performed by using the call() method.

Specified by:

set in interface StatisticalTest

Parameters:

x - List of instances

y - List of instances
