DT_augment: DT_augment design example.

In sommer: Solving Mixed Model Equations in R

DT_augment design example.

Description

This dataset contains phenotpic data for one trait evaluated in the experimental design known as augmented design. This model allows to obtain BLUPs for genotypes that are unreplicated by dividing the field in blocks and replicating 'check genotypes' in the blocks and unreplicated genotypes randomly within the blocks. The presence of check genotypes (usually cultivars) allows the adjustment of unreplicated genotypes.

Usage

data("DT_augment")

Format

The format is: chr "DT_augment"

Source

This data was generated by a potato study.
