BRISE_c.stat

For the contrast version of BRISE (“con”), computes within-sample sums of the rank matrix R (i.e. Ux, Uy) over all observations in X and Y, for congregated BRISE test.

internal

Implements the Block-wise Rank in Similarity Graph Edge-count
test (BRISE), a rank-based two-sample test designed for block-wise
missing data. The method constructs (pattern) pair-wise similarity graphs
and derives quadratic test statistics with asymptotic chi-square
distribution or permutation-based p-values. It provides both
vectorized and congregated versions for flexible inference.
The methodology is described in Zhang, Liang, Maile, and
Zhou (2025) <doi:10.48550/arXiv.2508.17411>.
