Method Detail

getParameter

double[] getParameter()

Get the parameters of determining this parametric covariance model. The parameters are usually free parameters which may be used in calibration.

Returns:

Parameter vector.

getCloneWithModifiedParameters

TermStructureCovarianceModelParametric getCloneWithModifiedParameters(double[] parameters)

Return an instance of this model using a new set of parameters. Note: To improve performance it is admissible to return the same instance of the object given that the parameters have not changed. Models should be immutable.

Parameters:

parameters - The new set of parameters.

Returns:

An instance of AbstractLIBORCovarianceModelParametric with modified parameters.
