(Pseudo) Random Number Generators (PRNG) are exceedingly important
in ALL computing scenarios.
How valid is your PRNG?
We can discuss endlessly the concept of a true random sequence
(and the math ain't easy) but in today's technical world only
the practical is important.
To test your PRNG just use the "diehard" suite:
https://webhome.phy.duke.edu/~rgb/General/dieharder.phpAmong other things, these tests examine clustering in
dimensions as high as 55. Whew~
These tests are considered definitive throughout the world.
But I am so terribly, terribly sorry, the "dieharder" suite
is available for GNU/Linux only.
Microslop Winblows users couldn't distinguish a rat's ass
from a true random number.
Haaaaaaa, ha, ha, ha, ha, ha, ha, ha!
Anyway, here is the result of Dieharder on my Intel
"rdrand" instruction:

Everything has passed the stringent tests.
Note the "p-value," but distro lackeys could not distinguish a
p-value from their own diminutive penis.
Haaaa, ha, ha, ha, ha, ha, ha, ha, ha, ha!
Please, post your own test results.
But distro lackeys cannot do anything unless they get permission
from the "mother ship."
Haaaa, ha, ha, ha, ha, ha, ha, ha, ha, ha!
