Class SimpleNoiseDistribution

java.lang.Object
com.compomics.util.experiment.mass_spectrometry.SimpleNoiseDistribution
public class SimpleNoiseDistribution extends Object
This class makes a simple modeling of the noise using a normal distribution on the log of the peak intensities and returns the associated binned cumulative probability for a given intensity.
