This Friday, Håkon Gjessing will present on “Heritability curves; a local measure of heritability”.
“We introduce a new measure of heritability that extends the traditional measure of heritability typically measured in twin and family models. Instead of basing the heritability (and environmental) components on standard correlations between family members, we use a "local" definition of correlation. Instead of estimating a single heritability, this allows us to measure how the heritability of a phenotype changes over the entire range of the phenotype. For instance, in an ADE twin model, the a^2, d^2, and e^2 components can change over the phenotype, and even switch to an ACE model within the same phenotype. We provide some simple examples as well as suggesting possible extensions to more complex family structures.
This is joint work with Geir D. Berentsen (NHH) and Francesca Azzolini, Hans J. Skaug, and Rolv T. Lie (UiB)”
