WebFeb 11, 2024 · Recent GWAS results suggest that, among all disease-associated SNPs, there are many more SNPs with small effect sizes than those with large effect sizes [32, 33]. Therefore, we use the following spike-and-slab prior to model the effect sizes of all SNPs: (13) where π 0 is the proportion of non-associated SNPs (0 ≤ π 0 ≤ 1) and δ 0 is the …
WebAccording to Cohen (1988, 1992), the effect size is low if the value of r varies around 0.1, medium if r varies around 0.3, and large if r varies more than 0.5. The Pearson correlation is computed using the following formula: Where. r = correlation coefficient.
