Class CalibratedModel

java.lang.Object

net.finmath.fouriermethod.calibration.CalibratedModel

public class CalibratedModel
extends Object

This class solves a calibration problem. The problem is defined in terms of:

• a generic container of market data OptionSurfaceData.
• a generic pricing model.
• a generic calibration algorithm.
• a generic pricer for claims.

The class supports both calibration in terms of:

• Prices
• Log-normal implied volatilities.
• Normal implied volatilities.

To change the calibration entity please change the convention in the option surface. The calibration entity (i.e. price/vol/normal vol) is directly detected from market data.

Method Detail

getCalibration

public CalibratedModel.OptimizationResult getCalibration()
                                                  throws SolverException

Solves the calibration problem thus providing a calibrated model.

Returns:

the calibrated model wrapped in an CalibratedModel.OptimizationResult.

Throws:

SolverException - Thrown if the calibration problem cannot be solved.
