Syntax

public interface IObjectiveModelEvaluation

The IObjectiveModelEvaluation type exposes the following members.

Properties

	Name	Description
	DegreeOfFreedom	Get the degree of freedom.
	FunctionEvaluations	Get the number of calls to function.
	Gradient	Get the Gradient vector. G = J'(y - f(x; p))
	Hessian	Get the approximated Hessian matrix. H = J'J
	IsGradientSupported	Gets a value indicating whether the gradient can be provided by the model.
	IsHessianSupported	Gets a value indicating whether the Hessian can be provided by the model.
	JacobianEvaluations	Get the number of calls to jacobian.
	ModelValues	Get the y-values of the fitted model that correspond to the independent values.
	ObservedY	Get the y-values of the observations.
	Point	Get the values of the parameters.
	Value	Get the residual sum of squares.
	Weights	Get the values of the weights for the observations.
