BIGFAM - variance components analysis from relatives without genotype [PDF]
Nature CommunicationsEstimating variance components of phenotypes provides a fundamental basis for understanding complex traits. However, most existing methods require genotype data, which is costly to obtain and often unavailable, limiting their scalability. To address this
