Presenter
Hermine Maes
Date first presented
June 2021 Virtual Workshop
Content
Discusses two alternative approaches to estimating variance components in twin models: (a) estimating the path coefficients from the latent variables to the phenotypes and fixing the variances of the latent variables; or (b) estimating the variances of the latent variables but fixing the path coefficients to the phenotypes at 1.
