　　In the linear model case, this integral can be solved in closed form, and the resulting likelihood or restricted likelihood can be maximized directly. For nonlinear multilevel models, however, the integral is usually unknown and must be approximated. Many methods have been proposed for such maximization approximation. Two basic methods are: 1） linearization, which approximates the integrated likelihood function using techniques such as Taylor series expansion, 2） integral approximation with numerical methods. These approaches are implemented in two SAS procedures, PROC GLIMMIX and PROC NLMIXED and two macros, ％GLIMMIX and ％NLMIXED, respectively.
　　Prior to the current version of SAS （SAS 9.2） （SAS Institute Inc., 2008）, PROC GLIMMIX is solely based on linearization methods. In version 9.2 of PROC GLIMMIX, linearization is the default estimation method, and two numerical integration methods——Laplace approximation method and adaptive Gauss-Hermite quadrature have been added as options. The linearization method is also called a pseudo-likelihood method, in which pseudo-data are generated from the original data, and likelihood function is approximated using Taylor series expansions （Schabenberger, 2005）. The essential idea of the linearization method is to approximate GLMM using normal linear mixed model estimates repeatedly. Among the various linearization methods available in the procedure, the default method is the restricted or residual pseudo-likelihood （REPL） （Wolfinger & OConnell, 1993）. The maximization of the pseudo-likelihood can be carried out by various optimization techniques in PROC GLIMMIX. The default optimization technique is the Newton-Raphson algorithm.
　　The major advantages of linearization-based methods include: First, they can fit models for which the joint distribution is difficult or impossible to ascertain. Second, compared with numerical integration methods, they allow a larger number of random effects to be estimated in the model. Third, the variance/covariance structure of the level-1 residual matrix （i.e., R matrix） can be readily accommodated. Fourth, the model is iteratively estimated based on the linear mixed model, thus both ML and REML are available for model estimation （Schabenberger, 2005）. In addition, in our experience, linearization based models are much faster to run.
　　The disadvantages of linearization-based methods include: First, they are based on iterative model estimation using pseudo-data constructed from the original data; as such, they do not have a real likelihood, and therefore -2LL or deviance statistic cannot be used for model comparisons. Second, PROC GLIMMIX does not support a broad array of variance/covariance structures of the R matrix that you can draw on with the PROC MIXED procedure （Schabenberger,
