Programs for testing of randomness

Click For Summary

Discussion Overview

The discussion revolves around the search for programs that can test the randomness of pseudorandom sequences of real numbers and short integer sequences. Participants explore various tools and methods for assessing randomness, including statistical tests and spreadsheet applications.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about programs specifically designed to test the randomness of pseudorandom sequences.
  • Another participant asks whether the desired analysis is for simple statistical tests or cryptographic purposes.
  • Suggestions include using spreadsheets to plot values and assess distribution and variance as measures of randomness.
  • There is a request for programs that can automatically analyze sequences and generate reports, rather than relying on manual calculations.
  • A participant mentions that while they do not know of tools specifically for the task, many existing programs can be programmed to perform the desired analysis.
  • There is also a mention of interest in testing short integer sequences and a request for libraries of test programs.

Areas of Agreement / Disagreement

Participants express varying levels of knowledge about specific programs, with no consensus on a single tool that meets the initial request. Some suggest general-purpose software while others seek more specialized solutions.

Contextual Notes

The discussion does not resolve the specific requirements for testing randomness, such as the definitions of randomness or the types of sequences being analyzed. There is also uncertainty regarding the capabilities of suggested tools.

Who May Find This Useful

Individuals interested in statistical analysis, cryptography, or those seeking to evaluate the randomness of numerical sequences may find this discussion relevant.

Hello! Do you know any programs that can test randomness of pseudorandom sequences of real numbers?
 
Technology news on Phys.org
Do you want a simple statistics test or some type of cryptographic analysis of the PNG?
 
You could use a spreadsheet. Plot the values and see if you get an even distribution. Variance should be a good measure of the randomness.

If this simple statistics tests can test sequences of real numbers, then they may be good for me. Do you know any links in Internet?

Thank you. But I ask for programs. May be you know any programs that can automatically do this. Do you know any links in Internet?
 
Any spreadsheet program (OpenOffice, Excel, etc.) should be able to compute basic statistics. So can programs like Octave, MATLAB, Mathematics, etc. Use google to find links.

Thank you. But may be you know programs that take a sequence of real numbers as input data and return any reports. I think that Excel can test dependence only.
 
No, I don't know of any tools which are designed to do only exactly what you want to do, but I know many tools which, among other things, are capable of being programmed to do exactly what you want to do. It's not hard.

May be you know any good programs that can test randomness of _short_ integer sequences (the library of test programs).
