Phenotype permutation

WebThe first operation in f is an expansion permutation, in which certain bits are repeated to bring the 32 bits up to 48 bits (the same length as the key for the round), and the order of bits is changed. The output of the expansion permutation is XORed with the key. The next operation is the so-called S-box substitution.

Alternatively, permutation procedure can be used and much preferred in association studies which automatically takes the cor-relation structure of SNPs into consideration. The idea of permutation is to randomly permute the phenotype hundreds to thousands of times. For each permutated phenotype, the association analysis will be repeated.

WebApr 4, 2024 · In this article, we propose a new permutation-assisted tuning procedure in lasso (plasso) to identify phenotype-associated SNPs in a joint multiple-SNP regression model in GWAS. The tuning parameter of lasso determines the amount of shrinkage and is essential to the performance of variable selection. WebApr 17, 2015 · A random phenotype is first generated for the reference data, drawing from the standard normal distribution. This is then permuted, and for each permutation the top χ 2 statistic is computed for every gene.

WebThere are two possible permutation criteria: permutation of the phenotype samples or permutation of the gene labels. In general, the label permutation method is preferred as it preserves gene-gene correlations.
