Unparalleled flexibility, speed and accuracy for linear mixed models
ASReml-R is ideal for teams that prioritise accuracy, value speed, and pride themselves on innovation.
ASReml-R is statistical analysis software that offers advanced capabilities for analyzing complex data sets. It incorporates REML estimation, which enables the precise estimation of model parameters and reduces bias often associated with maximum likelihood estimation in mixed models. This leads to improved precision in parameter estimation, increasing the reliability and accuracy of the statistical analysis.
Genomic Prediction and Selection
ASReml-R stands at the forefront of supporting breeding programs with advanced genomic prediction and selection capabilities. ASReml-R helps to make precise and informed decisions in selecting superior individuals for breeding. By leveraging cutting-edge statistical methodologies, ASReml-R can unlock hidden genetic potential and accelerate the genetic gain within breeding populations.
Complex Structures and Varied Effects
ASReml-R allows for nested and crossed effects, along with an array of complex structures on random effects and residuals. It accommodates spatial analyses, repeated measures, random regression, and correlated structures in breeding datasets.
Integration in the R Environment
ASReml-R is a tool for the R environment, leveraging the power and flexibility of R. Users can effortlessly combine ASReml-R's capabilities with other R packages, enabling a comprehensive and efficient analytical workflow.
Multi-Trait and Multi-Environment Analyses
ASReml-R supports multi-trait and multi-environment (MET) analyses, as well as complex matrices involved in genomic selection. It is the most flexible and fast LMM library/package available in R.
ASReml-R addresses various challenges such as high-dimensional models, incorporating pedigree and molecular data, managing bias from family lines, optimizing MET models, and improving the accuracy of breeding values.

ASReml-R 4.2 - processing speed gains
ASReml-R 4.2 delivers impressive gains in processing speed. These gains depend upon a variety of factors including: microprocessor, machine power, dataset size and type of analysis run, among others, and they will vary between users. Below are some example gains the ASReml team were able to quantify.
Additional notes: Computer specifications: Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz, 16 Gb of RAM, Ubuntu 20.04 LTS. Analyses were carried out setting asreml.options(threads = 1, use.blas = “standard”) in ASReml-R 4.2. Further speed improvements can be achieved by increasing the number of threads and enabling Intel’s Math Kernel Library (MKL).
