- Inheritance
- Object → Curve → NonlinearCurve → GaussianCurve
Remarks
Use the GaussianCurve class to represent a four-parameter Gaussian curve with the characteristic 'bell' shape. This curve is used to fit data that contains a peak. The peak is less pronounced than that of the Lorentz curve.
.
For details on how to fit a curve of this type, see the NonlinearCurveFitter class.
