binary_matrix_rank
(series, candidate, matrix_dimen: Tuple[int, int] = None)[source]¶ Independence of neighbouring sequences is compared to expected result
Independence is determined by the matrix rank of a subsequence, where it is split into multiple rows to form a matrix. The counts of different rank bins is referenced to a hypothetically truly random RNG.
Parameters: - sequence (array-like) – Output of the RNG being tested
- candidate (Value present in given sequence) – The value which is counted in each block
- matrix_dimen (Tuple[int, int]) – Number of rows and columns in each matrix
Returns: BinaryMatrixRankTestResult – Dataclass that contains the test’s statistic and p-value
