Class  Description 

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

GaussianFitter 
Fits points to a
Gaussian function. 
GaussianFitter.ParameterGuesser 
Guesses the parameters
norm , mean , and sigma
of a Gaussian.Parametric
based on the specified observed points. 
HarmonicFitter 
Class that implements a curve fitting specialized for sinusoids.

HarmonicFitter.ParameterGuesser 
This class guesses harmonic coefficients from a sample.

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}).
