Heritability estimates
Model | Family-based heritability (N = 364), h2 (SE) | SNP-based heritability (N = 34 130), h2 (SE) |
---|---|---|
1 (age and sex) | 0.76 (0.12) | 0.39 (0.02) |
2 (model 1 + height) | 0.75 (0.12) | 0.39 (0.02) |
3 (model 2 + intracranial volume) | 0.74 (0.13) | 0.40 (0.02) |
4 (model 2 + head width) | 0.82 (0.12) | 0.40 (0.03) |
h2, narrow-sense heritability; N, sample size; SE, standard error.
