Function tink_tests::z_test_crosscorrelation_uniform_strings

pub fn z_test_crosscorrelation_uniform_strings(
    bytes1: &[u8], 
    bytes2: &[u8]
) -> Result<(), TinkError>

Test that the cross-correlation of two byte strings of equal length points to independent and uniformly distributed strings. Returns non Ok status if the z test fails by more than 10 standard deviations.

With less statistics jargon: This xors two strings and then performs the z_test_uniform_string on the result. If the two strings are independent and uniformly distributed, the xor'ed string is as well. A cross correlation test will find whether two strings overlap more or less than it would be expected.

Note: Having a correlation of zero is only a necessary but not sufficient condition for independence.
