dt8bal.df

A very small, simple dataset with a balanced design, one fixed effect, and two traits. The design consists of 4 sire families, with 2 offspring per sire, one of each sex.

datasets

Dyadic mixed model analysis with multi-trait responses and
pedigree-based partitioning of individual variation into a range of
environmental and genetic variance components for individual and
maternal effects. Method documented in dmmOverview.pdf; it is an
implementation of dispersion mean model described by
Searle et al. (1992) "Variance Components", Wiley, NY.
