The paper compares methods for estimating heritability and genetic architecture using whole genome data and finds that larger imputation panels improve accuracy of causal variant frequency estimates.

This paper estimates narrow-sense heritability using identity-by-descent information in unrelated individuals and finds that IBD-based methods can capture rare variant contributions but are affected by stratification.

The paper tests quantitative gene-environment interactions in unrelated individuals using a new maximum likelihood method applied to UK Biobank IQ data, finding increased genetic variation with lower socioeconomic status.
