          Description

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.AnovaSignificanceTestResult  
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.
CombinationGenerator This class can be used to iterate over all combinations of r elements out of n.
Complex A class for complex numbers which consists of a real and an imaginary part.
ContingencyTableTools This class provides some helper tool for calculations around contingency tables like chi-squared tests etc.
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.
LinearRegression This class can be used to calculate the coefficients of a (weighted) linear regression.
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.
ROCData This container holds all ROC data points for a single ROC curve.
ROCDataGenerator Helper class containing some methods for ROC plots, threshold finding and area under curve calculation.
ROCPoint Objects of this class hold all information about a single ROC data point.
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.
StringToMatrixConverter This class provides functions to convert a matrix given in single line Matlab format to standard matrix representation and vice versa.
TestGroup Helper class containing all information about a group, i.e. the number of elements, the mean and variance value.
VectorMath This class provides basic operations on vectors like subtraction, multiply and division.
WeightedConfidenceAndLabel Helper class for finding thresholds for cost sensitive learning or calculating the AUC performance criterion.
WeightedConfidenceAndLabel.WCALComparator  
WindowFunction Window functions apply a weight to each value of a value series depending on the length of the series.
 

Enum Summary
ROCBias Specifies how roc plots are evaluate: - first count correct classifications, then count incorrect ones - first count incorrect classifications, then count correct ones - distribute them evenly.
 

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