Are you experiencing challenges in R with:
- multi level data modelling?
- modelling complex structures with a fast convergence?
- specifying covariance structure for both random and residual (repeated measures) terms;
- handling large sparse matrices?
Why not try ASReml-r, an r package designed to fit mixed models for large data sets, quickly and efficiently with unmatched flexibility. Perfect for data with hierarchical or nested structures as commonly seen in clinical designs.
Contact us for more information and to discuss a trial or demonstration. For industrial users, we can provide bespoke migration service from major mixed model package to ASReml-R.
