programs for testing of randomness

[nworm]

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).
