Improved heritability partitioning and enrichment analyses using summary statistics with graphREML.

Abstract excerpt

Heritability enrichment analysis using data from genome-wide association studies is often used to understand the functional basis of genetic architecture. Stratified linkage disequilibrium score regression (S-LDSC) is a widely used method-of-moments estimator for heritability enrichment, but S-LDSC has low statistical power compared with likelihood-based approaches. We introduce graphREML, a precise and powerful...
