Does xoshiro/xoroshiro PRNGs provide uniform distribution?

cz flag

It's not clear from the documentation if the sequence of integers produced by these PRNGs belongs to the uniform distribution.

Also it's look like there is a whole family of RNG algorithms called in a similar manner. Personally I'm mostly interested in xoshiro256** - but no information about distribution uniformity as well.

I don't think xoroshiro&co aim to be cryptographically secure. So they're probably off-topic here.

@CodesInChaos thanks, but what forum would be appropriate for this question?

The llinked page has: _"they pass all tests we are aware of"_, in effect claiming uniform distribution for all practical purposes except cryptography.

The distribution is very close to uniform for example the 256 long generators run through all $2^{256}-1$ non-zero values of 256-bit words before cycling. As is commented above however, these are definitely not suitable for cryptography.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
