In particular, the package is suited to fit\nquantitative genetic mixed models, often referred to as 'animal\nmodels'. Implements the average information algorithm as the\nmain tool to maximize the restricted log-likelihood, but with\nother algorithms available.", "License": "GPL-3 | file LICENSE", "Encoding":
