The paper introduces a decomposed FVE estimation framework to improve heritability estimates by accounting for heavy-tailed SNP effects and violations of the bounded-kurtosis condition.

The paper introduces a conditional SNP-heritability method to estimate heritability across subpopulations with different ancestral and environmental factors, showing how heritability of intelligence scores varies by socio-economic group.

This study argues that fixing the intercept in LDSC improves SNP heritability estimation by reducing bias and variance, but LDSC remains biased under population stratification.
