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(xi)-yi
for observed points
(xi, yi).
