    <p>Linear models are solved using a modification of the analytic solution developed by Bates and Pinheiro (1998).
Non-linear models are solved using adaptive quadrature following the methods in STATA's GLAMMM (Rabe-Hesketh &amp; Skrondal, 2006)
and Pineiro and Chao (2006). The posterior modes used in adaptive quadrature are determined following the method in lme4pureR (Walker &amp; B
