public final class FastCreditCurveCalibrator
extends IsdaCompliantCreditCurveCalibrator

Fast credit curve calibrator.

This is a fast bootstrapper for the credit curve that is consistent with ISDA in that it will produce the same curve from the same inputs (up to numerical round-off).

The CDS pricer is internally implemented for fast calibration.

Constructor Detail

FastCreditCurveCalibrator

public FastCreditCurveCalibrator(AccrualOnDefaultFormula formula)

Constructs a credit curve builder with the accrual-on-default formula specified.

The arbitrage handling 'ignore' is used.

Parameters:

formula - the accrual-on-default formula

FastCreditCurveCalibrator

public FastCreditCurveCalibrator(AccrualOnDefaultFormula formula,
                                 ArbitrageHandling arbHandling)

Constructs a credit curve builder with accrual-on-default formula and arbitrage handing specified.

Parameters:

formula - the accrual on default formulae

arbHandling - the arbitrage handling

Method Detail

standard

public static FastCreditCurveCalibrator standard()

Obtains the standard calibrator.

The original ISDA accrual-on-default formula (version 1.8.2 and lower) is used.

Returns:

the standard calibrator

calibrate

public NodalCurve calibrate(List<ResolvedCdsTrade> calibrationCDSs,
                            DoubleArray flactionalSpreads,
                            DoubleArray pointsUpfront,
