ASReml-R - Robust Statistical Analysis Software for Linear Mixed Models
ASReml-R is a powerful statistical analysis software designed for the R environment, specifically targeting linear mixed models (LMMs). This software provides advanced capabilities for analyzing complex and large datasets frequently encountered in fields like animal breeding, plant sciences, aquaculture, agriculture, and environmental sciences. Using Restricted Maximum Likelihood (REML) estimation, ASReml-R ensures a precise estimation of model parameters, minimizing biases typically linked with maximum likelihood estimation in mixed models. Version 4.2 of ASReml-R introduces significant enhancements in speed, offering genomic predictions up to 85 times faster and streamlining complex multi-trait and multi-environment analyses by up to 40 times. ASReml-R supports a wide array of complex data structures, including nested and crossed effects, spatial analyses, and multi-environment trials. Its seamless integration in the R environment facilitates comprehensive analysis through compatibility with other R packages, making it an indispensable tool for researchers aiming to unlock the full potential of their data.ASReml-SA - Statistical Software for Linear Mixed Models
ASReml-SA is a sophisticated statistical software developed for the analysis of linear mixed models using advanced Residual Maximum Likelihood (REML) methodologies. The software is designed to handle complex, large, and unstructured data sets effectively and is widely used in fields such as animal breeding, plant science, agriculture, environmental science, and medical research. It enables the formulation of reliable estimates in mixed models and supports an array of data types including balanced, unbalanced, longitudinal, and spatial data. The latest version, ASReml-SA 4.2, features notable improvements in processing speed and memory allocation, facilitating the execution of larger data sets through enhanced parallel processing capabilities. This tool is essential for researchers and data analysts seeking robust solutions for genetic evaluation, breeding program analysis, and other applications that require intricate data handling.
CycDesigN - Experimental Design Software
