Programs for testing of randomness

In summary, the conversation discusses different programs that can test the randomness of pseudorandom sequences of real numbers. Recommendations include using a spreadsheet to plot values and measure variance, or using other programs such as Octave or MATLAB. The conversation also mentions the possibility of using Google to find links to suitable programs. The discussion ends with a mention of tools that can be programmed to perform specific tests, and the possibility of finding a library of test programs for short integer sequences.

Hello! Do you know any programs that can test randomness of pseudorandom sequences of real numbers?

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).
 

Related to Programs for testing of randomness

1. What is the purpose of programs for testing of randomness?

Programs for testing of randomness are designed to determine the degree of randomness in a set of data or numbers. They are commonly used in scientific research, statistical analysis, and quality control to ensure that data is truly random and not influenced by any external factors.

2. How do these programs work?

These programs use various statistical tests to analyze a set of data and determine if it exhibits a pattern or follows a specific distribution. These tests compare the data to an expected pattern of randomness and generate a result indicating the level of randomness.

3. Can programs for testing of randomness be used for all types of data?

No, these programs are typically designed for specific types of data, such as numerical data. They may not be applicable to qualitative or categorical data.

4. Are these programs reliable in determining randomness?

The reliability of these programs depends on the specific tests and algorithms used. It is important to choose a program that has been extensively tested and validated by other scientists.

5. What are some common types of tests used in programs for testing of randomness?

Some common tests used in these programs include the Chi-square test, Kolmogorov-Smirnov test, and Runs test. These tests assess different aspects of randomness, such as uniformity, independence, and randomness within a sequence.
