WebDec 1, 2005 · Permutation methods have become popular to estimate FDR in genomic studies. The purpose of this paper is 2-fold. First, we investigate theoretically and empirically whether the standard permutation-based FDR estimator is biased, and if so, whether the bias inappropriately favors or disfavors any method. WebApr 3, 2024 · The main challenge is the computational complexity, which is extremely high when considering many hypotheses, and when using many permutations. Permutation-based closed testing for the TDP so far mostly focused on Simes-based test procedures, while sum tests were approached under independence or with worst-case distributions … fss opening mailboxes

WebThe permutation feature importance depends on shuffling the feature, which adds randomness to the measurement. When the permutation is repeated, the results might vary greatly . Repeating the permutation and averaging the importance measures over repetitions stabilizes the measure, but increases the time of computation. WebWhen considering the transition probability matrix of ordinal patterns, transition permutation entropy (TPE) can effectively extract fault features by quantifying the irregularity and complexity of signals. However, TPE can only characterize the complexity of the vibration signals at a single scale. Therefore, a multiscale transition permutation entropy (MTPE) … WebJan 4, 2024 · A more thorough explanation of randomization tests and cluster-based statistics can be found in the Cluster-based permutation tests on event-related fields and the Cluster-based permutation tests on time-frequency data tutorials.
