Package elki.math

Mathematical operations and utilities used throughout the framework.

Class Summary

Class	Description
DoubleMinMax	Class to find the minimum and maximum double values in data.
IntegerMinMax	Class to find the minimum and maximum int values in data.
MathUtil	A collection of math related utility functions.
Mean	Compute the mean using a numerically stable online algorithm.
MeanVariance	Do some simple statistics (mean, variance) using a numerically stable online algorithm.
MeanVarianceMinMax	Class collecting mean, variance, minimum and maximum statistics.
PearsonCorrelation	Class to compute the Pearson correlation coefficient (PCC) also known as Pearson product-moment correlation coefficient (PPMCC).
Primes	Class for prime number handling.
SinCosTable	Class to precompute / cache Sinus and Cosinus values.
SinCosTable.FullTable	Table that can't exploit much symmetry, because the steps are not divisible by 2.
SinCosTable.HalfTable	Table that exploits just one symmetry, as the number of steps is divisible by two.
SinCosTable.QuarterTable	Table that exploits both symmetries, as the number of steps is divisible by four.
StatisticalMoments	Track various statistical moments, including mean, variance, skewness and kurtosis.
