In dmm: Dyadic Mixed Model for Pedigree Data

Description

Example dataset from the program package 'QUERCUS', developed by Ruth G. Shaw and Frank H. Shaw. Known to 'quercus' as the 'demo2' dataset.

Usage

data(quercus.df)

Format

A data frame with 180 observations on the following 6 variables.

Details

This is a simulated dataset suitable for a 3-component analysis, the components being environmental variance, additive genetic variance, and dominance genetic variance. It needs pre-processing with function mdf() to add base animals, to combine the two traits into a matrix, and to calculate additive and dominance relationship matrices.
