%description
Fit generalized linear mixed models (GLMMs) with normal random effects
using first-order Laplace, fully exponential Laplace (FEL) with mean-only
corrections, and FEL with mean and covariance corrections in the E-step of
an expectation-maximization (EM) algorithm. The current development
version provides a matrix-based interface (y, X, Z) and supports binary
logit and probit, and Poisson log-link models. An EM framework is used to
update fixed effects, random effects, and a single variance component
tau^2 for G = tau^2 I, with staged approximations (Laplace -> FEL
mean-only -> FEL full) for efficiency and stability. A pseudo-likelihood
engine glmmFEL_pl() implements the working-response / working-weights
linearization approach of Wolfinger and O'Connell (1993)
<doi:10.1080/00949659308811554>, and is adapted from the implementation
used in the 'RealVAMS' package (Broatch, Green, and Karl (2018))
<doi:10.32614/RJ-2018-033>. The FEL implementation follows Karl, Yang, and
Lohr (2014) <doi:10.1016/j.csda.2013.11.019> and related work (e.g.,
Tierney, Kass, and Kadane (1989) <doi:10.1080/01621459.1989.10478824>;
Rizopoulos, Verbeke, and Lesaffre (2009)
<doi:10.1111/j.1467-9868.2008.00704.x>; Steele (1996)
<doi:10.2307/2532845>). Package code was drafted with assistance from
generative AI tools.
