Class FloatStatistic



  • public class FloatStatisticextends Object
    Basic statistics operations on matrices. Computation of covariance, correlation, distance matrix. Random sampling views. Conversion to histograms with and without OLAP cube operators. Conversion to bins with retrieval of statistical bin measures. Also see cern.jet.stat and hep.aida.tfloat.bin, in particular DynamicFloatBin1D.
