Sentence examples for using the permutation approach from inspiring English sources

Sparsity parameters are selected using the permutation approach presented in [18] of which the code is provided in PMA package.

Finally, using the permutation approach separately in the AD and in the control samples, we were able to detect a large set of changes in the miRNA-target correlations in AD brain.

We found however that FDR estimates using the permutation approach were very similar to those estimated using the q-value framework at the significance levels of relevance (Figure S3).

†Probability of distribution was estimated by using the permutation approach (pexact).

The aim of this work is to extend the comparison of survival at multiple time points, using the multivariate permutation approach originally introduced by Pesarin [ 4].

This is reasonable because the power of the individual tests for lobular cases versus controls is weak; unlike Bonferroni procedures, for the permutation approach that we use, a completely meaningless test (power ≈ 0) does not affect the other tests at all because it will never affect the distribution of the minimum P-value statistic in the lower α tail.

The permutation approach offers various advantages.

The significance of R1 was assessed using a permutation approach: the two-sided p value is the proportion of permutations (where spouses are shuffled) in which the mean R1 of permuted couples is more extreme than the mean R1 of real couples.

Because the analytical q-value estimates assume independence of the underlying tests, which does not necessarily apply to neighboring probes that are spatially correlated, we also estimated the FDR using a permutation approach that preserves the potential correlation structure of proximal probes.

Since CpG sites within the same CpG-island may exhibit similar methylation profiles, and given that 7,528 CpG islands contained more than one CpG site, we also estimated the FDR using a permutation approach that would take the correlations of CpG sites into account.

Using a permutation approach the observed summary statistic for a particular SNP set is compared to an empirical distribution for the summary statistics of random samples of SNP sets of same size.
