This method calculates the mean of a data series

Parameters:

data1D -

Returns:

Double Mean

calcVariance

private double calcVariance(Vector<Double> data1D)

This method calculates the variance of a data series

Parameters:

data1D -

Returns:

Double Variance

calcVariance

private double calcVariance(Vector<Double> data1D,
                            double mean)

This method calculates the variance of a data series

Parameters:

data1D, - mean

Returns:

Double Variance

calcStandardDeviation

private double calcStandardDeviation(Vector<Double> data1D)

This method calculates the standard deviation of a data series

Parameters:

data1D -

Returns:

Double standard deviation

run

public IResult run(IWorkPackage wp)

Description copied from interface: IOperator

This method contains the entire logic (algorithm) of the operator. An IOperator does not declare any class members, since the execution of this code must be thread-safe.

Specified by:

run in interface IOperator

Specified by:

run in class AbstractOperator

Parameters:

wp - the parameters and sources

Returns:

a IResult containing all processed data

getAlphabet

private String[] getAlphabet(int alphabetSize)

This method gets back the alphabet

Parameters:

index -

Returns:

character

getBreakpointsLUT

private double[] getBreakpointsLUT(int alphabetSize)

This method gets back a LUT of breakpoints (levels) in order to segment a signal into symbols

Parameters:

alphabetSize -

Returns:

a double array

getName

public String getName()

Description copied from interface: IOperator

Gets the unique name of the IOperator by returning the "GlobalName" element from the resources[][] of the associated IOperatorDescriptor.

Specified by:

getName in interface IOperator

Specified by:

getName in class AbstractOperator

Returns:

the unique name of the operator

getType

public OperatorType getType()

Description copied from interface: IOperator

Gets the type of the operator listed in an enumeration.

Specified by:

getType in interface IOperator

Specified by:

getType in class AbstractOperator

Returns:

the OperatorType
