Constructor Detail

MultiturnBetaSensitivityMatrixContributor

public MultiturnBetaSensitivityMatrixContributor(MultiturnMeasurement multiturnMeasurement)

Method Detail

calcCorrectorSensitivityMatrix

public Jama.Matrix calcCorrectorSensitivityMatrix()

Specified by:

calcCorrectorSensitivityMatrix in interface SensitivityMatrixContributor

Returns:

the part of the sensitivity-matrix corresponding to the corrector-gains.

calcMonitorSensitivityMatrix

public Jama.Matrix calcMonitorSensitivityMatrix()

Specified by:

calcMonitorSensitivityMatrix in interface SensitivityMatrixContributor

Returns:

the part of the sensitivity-matrix corresponding to the monitor-gains.

calcPerturbedColumn

public PerturbedColumn calcPerturbedColumn(double delta,
                                           java.lang.Double normalizationFactor)

Specified by:

calcPerturbedColumn in interface SensitivityMatrixContributor

Parameters:

delta - the variation that was used to trim the parameter. This is needed by the method to calc the gradient correctly.

normalizationFactor - the normalization factor to use to calc the column. If none is given (null) then the own normalization-factor must be calculated by the method.

Returns:

a column, which represents the perturbation of the actual values in comparison to the default one.

getDifferenceVector

public Jama.Matrix getDifferenceVector()

Specified by:

getDifferenceVector in interface SensitivityMatrixContributor

Returns:

the difference-vector between measurement-model, corresponding to the rows in the other matrices

getMatrixRowCount

public int getMatrixRowCount()

Description copied from interface: SensitivityMatrixContributor

this method can be called to determine the designated number of rows of the matrices that will be produced by this contributor.

Specified by:

getMatrixRowCount in interface SensitivityMatrixContributor

Returns:

the number of rows of the matrices.

getMeasurement

public Measurement getMeasurement()

Specified by:

getMeasurement in interface SensitivityMatrixContributor

Returns:

the measurement to which this contributor is related to.

getName

public java.lang.String getName()

Specified by:

getName in interface SensitivityMatrixContributor

Returns:

a name for the contributor, which can be displayed

initUnperturbed

public void initUnperturbed()

Description copied from interface: SensitivityMatrixContributor

this method is called by the SensitivityMatrixManagerImpl, to make it possible for the contributors to store their unperturbed values, in order to be able to correctly calculate the perturbed values later on.

Specified by:

initUnperturbed in interface SensitivityMatrixContributor

setMultiturnMeasurement

public void setMultiturnMeasurement(MultiturnMeasurement multiturnMeasurement)

setMachineElementsManager

public void setMachineElementsManager(MachineElementsManager machineElementsManager)

Description copied from interface: MachineElementsManagerAware

by the use of this method the MachineElementsManager is injected if the class is configured by the AlohaBeanFactory

Specified by:

setMachineElementsManager in interface MachineElementsManagerAware

setNoiseWeighter

public void setNoiseWeighter(NoiseWeighter noiseWeighter)

Description copied from interface: NoiseWeighterAware

this method is used by the AlohaBeanFactory to inject the NoiseWeighter instance

Specified by:

setNoiseWeighter in interface NoiseWeighterAware

Parameters:

noiseWeighter - the NoiseWeighter to be used by the class

getDifferenceVectorErrors

public Jama.Matrix getDifferenceVectorErrors()

Description copied from interface: SensitivityMatrixContributor

This method must return a vector which has the same dimensions as the difference-vector as returned by SensitivityMatrixContributor.getDifferenceVector(). This vector shall represent the errors on the difference vector. It will be used to estimate the errors on the fitted parameters.

Specified by:

getDifferenceVectorErrors in interface SensitivityMatrixContributor

Returns:

a vector representing the errors on the difference vector.
