Ritable: Pedigree-Based Heritability Estimation for Family Cohort Studies

Provides profile-likelihood variance-components estimation of narrow-sense heritability (h2) for quantitative traits in family cohort studies. Additive genetic relationship matrices are built from pedigrees via kinship2. Phenotypes are inverse-normal transformed internally. Likelihood-ratio tests use a one-sided chi-squared boundary correction equivalent to SOLAR Eclipse. Ninety-five percent confidence intervals are derived from the profile likelihood rather than Wald approximations. Batch estimation over many traits returns tidy data frames ready for downstream visualisation.
