Cluster membership was associated with mutation burden, which suggests that the underlying mutation mechanisms may be coupled to the frequency of mutagenic events (P = 3.8 × 10 −2, Mann-Whitney U test). SpletA Wilcoxon–Mann–Whitney Test for Latent Variables. We propose an extension of the Wilcoxon–Mann–Whitney test to compare two groups when the outcome variable is latent. We empirically demonstrate that the test can have superior power properties relative to tests based on Structural Equation Modeling for a variety of settings.
