Remarks

Use the FiveParameterLogisticCurve class to fit a five parameter logistic curve to data. This type of curve is often used to represent growth processes, or a transition of a quantity from one level to another level.

With the FourParameterLogisticCurve curve, the change from the initial value and towards the final value are fairly symmetrical. When the data does not show this behavior, the resulting fit may not be adequate. The FiveParameterLogisticCurve curve remedies this situation by adding an asymmetry factor:

For details on how to fit a curve of this type, see the NonlinearCurveFitter class.
