MutableUnivariateStatistics

public class UnivariateStatistics

extends java.lang.Object

UnivariateStatistics calculates statistics of a series of measurements. UnivariateStatistics is immutable. Use MutableUnivariateStatistics if you need to update the statistics with measurements. Only simple statistics are generated (mean and standard deviation).
