andrewpbray/lmmoptim: Optimization routine for linear mixed models

An implementation of the optimization algorithm described in, "Approximately Exact Calculations for Linear Mixed Models" by Lavine and Hodges (2015). The algorithm finds arbitrarily precise bounds on the global min/max of the restricted likelihood of linear mixed models with two variances. Also included are functions to visualize the likelihood function and the optimization process.
