Detailed Description
LOWESS (locally weighted scatterplot smoothing).
A smoothing technique that fits simple models (linear, quadratic) to localized subsets of the data, point by point. This is particularly useful for smoothing intensities in spectra or chromatograms. In this case, the window size for the smoothing should be setted proportional to the peak width (see LowessSmoothing parameters).
Parameters of this class are:| Name | Type | Default | Restrictions | Description |
|---|---|---|---|---|
| window_size | int | 10 | The number of peaks to be included for local fitting in one window. |

This method is used to update extra member variables at the end of the setParameters() method.
Also call it at the end of the derived classes' copy constructor and assignment operator.
The default implementation is empty.
Reimplemented from DefaultParamHandler.
