资 源 简 介
A histogram library for Java that accepts large datasets with any distribution or range with a very small memory footprint, needs no pre- or post-processing, and provides several statistical functions.
Most current version here: https://github.com/flaptor/hist4j
Hist4j has the following features:
It adapts to any data distribution, keeping a more or less constant resolution throughout the data range by increasing the resolution where the data is more dense.
It can process large amounts of data with a very small memory footprint.
It doesn"t need pre- or post-processing to deliver statistics about the data seen so far.
The following statistics are currently available:
The cumulative density function for a given data point.
The data point that splits the data set at a given percentile.
