| Class Summary | |
|---|---|
| CurveFitter | Fitter for parametric univariate real functions y = f(x). |
| GaussianDerivativeFunction | The derivative of GaussianFunction. |

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. |
This package provides 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 residuals
f(xi)-yi for observed points
(xi, yi).
