Accounting for Mutation Effects in the Additive Genetic Variance-Covariance Matrix and Its Inverse

Procedures for calculating the additive genetic variance-covariance matrix and its inverse are adapted to accommodate the occurrence of mutations in the genome. The inverse matrix can be used in mixed ...

Comparing G: multivariate analysis of genetic variation in multiple populations

The distribution of genetic variation among multiple traits is a key determinant of how a population will respond to selection (Lande, 1979; Schluter, 1996; Arnold et al., 2001). For the prediction of ...

Converting a covariance matrix from local currencies to a common currency

This short paper demonstrates how a covariance matrix estimated using log returns of multiple assets in their respective base currencies can be converted directly into a covariance matrix in a single ...
