Starting from a set of n objects numbered from 1 through n and arranged in numerical order, we can make a permutation of them to some other order; the total number of distinct permutations that are possible is n! (choose the first object n ways, then choose the second in n-1 ways, ...
We can userecursionto solve this problem. The idea is to add each element to the output and recur for the remaining items with one less element. To avoid printing permutations, construct each tuple in the same order as array elements. Then if the combination of the given size is found, p...
A fringe subtree of a rooted tree is a subtree induced by one of the vertices and all its descendants. We consider the problem of estimating the number of distinct fringe subtrees in random trees under a generalized notion of distinctness, which allows for many different interpretations of what...

false discovery rate (FDR). This method adjusts thep-values based on their rank and the total number of tests, ensuring that the proportion of false positives among the significant results remains low. To further validate the results, permutation testing was also performed (1,000 permutations)....
used to order genes in a descending manner, (3) enrichment score (ES) was computed using a Kolmogorov–Smirnov running sum statistics for each gene set, and (4) significance of the ES was computed using a distribution of null hypothesis which was generated by doing 1000 random permutations. ...
MRI data were acquired on a GE 3 Tesla Signa Excite HDxMRI scanner, equipped with an eight-channel phased array head coil at York Neuroimaging Centre, University of York. For each participant, we acquired a sagittal isotropic 3D fast spoiled gradient-recalled echo T1-weighted structural scan ...
(permutation test, 1000 permutations, p = 0) (G) Pseudo-time analysis of naive, sham, and MCAo with normalized cell density in each condition for each region. (H) Phase portrait showing unspliced and spliced counts in neutrophils of gene S100a6 for naive, sham and MCAo respectively. (I...
of the genes on the PanCancer Immune Profiling array. All 760 genes on the array were used for clustering the MicMa cohort, while 509 genes, which corresponds to genes (out of the 760) found in all datasets, were used to cluster the METABRIC. Annotations of the samples on the top of ...
assignments were removed. Operational taxonomic units were then clustered under a 0.03 cutoff level and phylotypes were determined by taxonomic classification. Rarefaction curves were calculated using rarecurve function in the vegan R package v2.6-13 with a subsampling of 20 and 100 permutations. ...
