Interface  Description 

ParametricRealFunction 
An interface representing a real function that depends on one independent
variable plus some extra parameters.

Class  Description 

CurveFitter 
Fitter for parametric univariate real functions y = f(x).

GaussianDerivativeFunction 
The derivative of
GaussianFunction . 
GaussianFitter 
Fits points to a Gaussian function (that is, a
GaussianFunction ). 
GaussianFunction 
A Gaussian function.

GaussianParametersGuesser 
Guesses the parameters (
a , b , c , and d )
of a ParametricGaussianFunction based on the specified observed
points. 
HarmonicCoefficientsGuesser 
This class guesses harmonic coefficients from a sample.

HarmonicFitter 
This class implements a curve fitting specialized for sinusoids.

HarmonicFunction 
Harmonic function of the form
f (t) = a cos (ω t + φ) . 
ParametricGaussianFunction 
A Gaussian function.

PolynomialFitter 
This class implements a curve fitting specialized for polynomials.

WeightedObservedPoint 
This class is a simple container for weighted observed point in
curve fitting . 
Curve fitting is a special case of a least squares problem
were the parameters are the coefficients of a function f
whose graph y=f(x)
should pass through sample points, and
were the objective function is the squared sum of residuals
f(x_{i})y_{i}
for observed points
(x_{i}, y_{i}).
