                                   AnnuityMapping.AnnuityMappingType annuityMappingType)

Create the calibrator.

Parameters:

referenceDate - The reference date of the cube.

cashPayerPremiums - The lattice containing market targets for cash settled payer swaptions. The lattice needs to be quoted in QuotingConvention.PRICE.

cashReceiverPremiums - The lattice containing market targets for cash settled receiver swaptions. The lattice needs to be quoted in QuotingConvention.PRICE.

physicalATMSwaptions - Lattice containing at-the-money values of physically settled swaptions.

model - The model providing context.

annuityMappingType - The type of annuity mapping to be used for calibration.

Method Detail

buildCube

protected VolatilityCube buildCube(String name,
                                   double[] parameters)

Description copied from class: AbstractCubeCalibration

Build the cube from a set of parameters. These need to be an array of all parameters to be calibrated.

Specified by:

buildCube in class AbstractCubeCalibration

Parameters:

name - The name the cube will carry.

parameters - The parameters of the cube as array.

Returns:

The volatility cube.

initializeParameters

protected void initializeParameters()

Description copied from class: AbstractCubeCalibration

Prepare the parameters for the start of the calibration.

Specified by:

initializeParameters in class AbstractCubeCalibration

applyParameterBounds

protected double[] applyParameterBounds(double[] parameters)

Description copied from class: AbstractCubeCalibration

Apply bounds to parameters. Such as volatility larger zero.

Specified by:

applyParameterBounds in class AbstractCubeCalibration

Parameters:

parameters - The raw parameters of the cube as array.

Returns:

The parameters with their respective bounds applied.
