What would be best way to evaluate randomness quality? This is something I've been thinking a lot. Yes, there are 'ent' and others, but I am more after trend of randomness quality over weeks and months.



Compress it.

Truly random data is incompressible. Any alogirithm should work.


Random data is incompressible, but not everything incompressible (as far as practical compression algorithms are concerned) is random.


Do you have any examples of that?
