WebJun 1, 2024 · 2.1 P-values and Their Negative Log Transformation. The null hypothesis of an association test is that there is no linkage disequilibrium between a genetic marker and a trait of interest. GWAS tests the hypothesis for all genetic markers across the genome either by testing the markers one at a time in single-locus model [], or testing all the markers … WebGenome-wide complex trait analysis ( GCTA) Genome-based restricted maximum likelihood ( GREML) is a statistical method for variance component estimation in genetics which quantifies the total narrow-sense (additive) contribution to a trait's heritability of a particular subset of genetic variants (typically limited to SNPs with MAF >1%, hence ...
