Interface Summary

PeakFinder

PeakFinder are objects which searches peaks in a given series of values.

Class Summary

AnovaCalculator	Determines if the null hypothesis (all actual mean values are the same) holds for the given values.
AnovaCalculator.Group	Helper class containing all information about a group, i.e. the number of elements, the mean and variance value.
Averagable	Superclass for all objects which can be averaged.
AverageVector	Handles several averagables.
BinaryPeakFinder	Generates the amplitude and index point of the highest peaks in the series.
Complex	A class for complex numbers which consists of a real and an imaginary part.
FastFourierTransform	Performs a FastFourierTransform on an array of complex values.
FDistribution	The FDistribution depends on two given degrees of freedom.
LiftDataGenerator	Helper class containing some methods for Lift plots.
MathFunctions	This class provides mathematical functions not already provided by java.lang.Math: tanh() : tangens hyperbolicus, y = tanh(x) = (e^x - e^-x) / (e^x + e^-x)
Peak	A peak with a index and a value.
ROCDataGenerator	Helper class containing some methods for ROC plots, threshold finding and area under curve calculation.
RunVector	Collects the average vectors of a run.
SignificanceTestResult	This class encapsulates the result of a statistical significance test.
SimplePeakFinder	This simple implementation returns a peak if the specified number of neighbors is smaller than the current value.
SpectrumFilter	Creates a series of peaks (a spectrum) from the series of complex values calculated for example by a fourier transform.
WeightedConfidenceAndLabel	Helper class for finding thresholds for cost sensitive learning or calculating the AUC performance criterion.
WindowFunction	Window functions apply a weight to each value of a value series depending on the length of the series.

Exception Summary

SignificanceCalculationException

This exception is thrown during the calculation of significance values like paired t-tests or ANOVA.
