MMaDe

Mixed models and design of experiments.

Our Aim

Is to foster and support the use of linear and generalised linear mixed models, with particular application to plant and animal breeding data. 

Packages

The following packages are available for download from their respective pages:

ASExtras4: Utility functions for ASReml objects: diagnostic tools for the meta-analysis of a series of spatially defined field experiments.​

TPSbits: Creates structures to enable ASReml-R to fit the 2D tensor-product splines of Rodriguez-Alvarez et al (2018, Spatial Statistics 23, 52-71). Also enables extraction and plotting of the components of the splines.

Optimal Design: The od package generates optimal experimental designs under the linear mixed model.

Pedicure: The pedicure package provides tools for pedigrees and genetic marker matrices.

Resources

The following resources are available:

Reference Manual: A comprehensive guide to the complete functionality of ASReml-R Version 4.

Navigation document: A helpful guide to assist existing users in transitioning from ASReml-R Version 3 to Version 4.
