Detailed Description
Normal distribution model for elution profiles.
To be used in combination with the Levenberg-Marquardt algorithm fitting algorithm.
Parameters of this class are:| Name | Type | Default | Restrictions | Description |
|---|---|---|---|---|
| cutoff | float | 0 | Low intensity cutoff of the model. Peaks below this intensity are not considered part of the model. | |
| interpolation_step | float | 0.1 | Sampling rate for the interpolation of the model function | |
| intensity_scaling | float | 1 | Scaling factor used to adjust the model distribution to the intensities of the data | |
| bounding_box:min | float | 0 | Lower end of bounding box enclosing the data used to fit the model. | |
| bounding_box:max | float | 1 | Upper end of bounding box enclosing the data used to fit the model. | |
| statistics:mean | float | 0 | Centroid position of the model. | |
| statistics:variance | float | 1 | The variance of the model. | |
| lma:scale_factor | float | 1000000 | Scale factor for the intensity of the model. | |
| lma:standard_deviation | float | 5 | The standard deviation (variance) of the model. | |
| lma:expected_value | float | 1200 | The expected value (centroid position) of the model. |
