Phenotype permutation

WebIf a permutation test is to be split across multiple processors, it is important to ensure that the random number seeds are set to be different for the different jobs, using the function set.seed. Otherwise, the multiple jobs may give precisely the same results. In version 1.12, we added the ability to have scanone and Webexpressionandthegiven phenotype and(3)aglobaltestlookingfor associations between gene expression in predefined gene sets and a target variable (Goeman et al., 2004). Until now, results coming from different datasets and statistical methods have only been compared on the level of lists of differen-tially expressed genes.

A major computational hurdle of permutation testing is the potentially large number of random permutations that need to be used in order to estimate small p-values accurately. To cope with this computational burden, we use an efficient p-value evaluation procedure based on the Stochastic Approximation … Zobraziť viac We compared the p-values of the permutation test to the p-values calculated by assuming the parametric LMM. We analyzed methylation measurement profiles from the … Zobraziť viac In order to show the generality of the discrepancy phenomenon, we analyzed gene expression data in the GTEx dataset (see Methods). We … Zobraziť viac Running time is a major obstacle to performing permutation tests.
