HE (Haseman-Elston) Regression is a method for estimating heritability, which for large datasets (>10,000 samples) is substantially faster than REML (although the estimates will be less precise). It is also able to estimate heritability using only selected pairs of samples, which provides a way to test for and protect against ...

Web28. dec 2024. · The SNP heritability estimates are presented in Table 2. For case control studies, we present estimates on the observed scale, which can be easily converted to the liability scale if the disease prevalence in the population is known [Lee et al.
