Description

Class Summary
CurveFitter<T extends ParametricUnivariateFunction> | 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 | Polynomial fitting is a very simple case of `curve fitting`.
WeightedObservedPoint | This class is a simple container for weighted observed point in `curve fitting`.

## Package org.apache.commons.math3.fitting Description

Classes to perform 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 the residuals `f(xi) - yi` for observed points `(xi, yi)`.
