• Logit.Parametric

  public Logit.Parametric()

Method Detail

• value

  public double value(double x,
             double... param)
               throws NullArgumentException,
                      DimensionMismatchException

  Computes the value of the logit at x.

  Specified by:

  value in interface ParametricUnivariateFunction

  Parameters:

  x - Value for which the function must be computed.

  param - Values of lower bound and higher bounds.

  Returns:

  the value of the function.

  Throws:

  NullArgumentException - if param is null.

  DimensionMismatchException - if the size of param is not 2.

• gradient

  public double[] gradient(double x,
                  double... param)
                    throws NullArgumentException,
                           DimensionMismatchException

  Computes the value of the gradient at x. The components of the gradient vector are the partial derivatives of the function with respect to each of the parameters (lower bound and higher bound).

  Specified by:

  gradient in interface ParametricUnivariateFunction

  Parameters:

  x - Value at which the gradient must be computed.

  param - Values for lower and higher bounds.

  Returns:

  the gradient vector at x.

  Throws:

  NullArgumentException - if param is null.

  DimensionMismatchException - if the size of param is not 2.
