Unparalleled flexibility, speed and
accuracy for linear mixed models
Powerful Analysis
ASReml-R is statistical analysis software that offers advanced capabilities for analysing 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. Its robust mixed model capabilities improve the accuracy of your estimates, so you can make better-informed decisions and trust the outcomes of your 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
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.
Flexible and Adatable
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.

Frequently Asked Questions
What Does REML Stand for in Statistical Analysis Software?
REML stands for Restricted (or Residual) Maximum Likelihood. It is a method for fitting a linear mixed model, where variance components are estimated by minimizing the restricted log-likelihood function.
What is the Difference Between REML and ML in Statistical Analysis Software?
ML (Maximum Likelihood estimation) is where observed data is used to estimate the parameters of an assumed probability distribution. REML and ML differ on how they treat the nuisance parameters (fixed effects).
Which Industries Would Benefit from using ASReml-R Statistical Software?
ASReml-R statistical software is a popular tool commonly used in agriculture, food science and Animal breeding to name a few. We have a helpful case study available if you would like to read a practical example of how ASReml-R can be used in your business.
How Does ASReml-R Differ From ASReml-SA?
ASReml-SA uses a text file user interface and can access more workspace, making it useful for very large problems. ASReml-R is more convenient for regular users of the R environment and it makes it easier to manipulate data.
Both versions of the ASReml statistical analysis software are powerful tools for fitting mixed models and are based on the same computational core.
How do you Use ASReml-R statistical modelling software?
We have an array of resources available to help you use ASReml-R to enhance your research including tutorial videos, E-learning and user guides.
How much does ASReml-R cost?
Academic licences start from £375, providing full access to ASReml-R’s capabilities for research and teaching use. Commercial and enterprise licences are tailored to your organisation’s requirements, including team size, support, and deployment options.
