%description
Provides tools for Markov chain Monte Carlo (MCMC) and Maximum A
Posteriori (MAP) estimation utilizing the 'RTMB' package. It supports
various statistical models including generalized linear mixed models,
factor analysis, item response theory, and multidimensional unfolding. The
package allows users to easily transition between frequentist and Bayesian
paradigms using a unified interface. Automatic differentiation and Laplace
approximation follow Kristensen et al. (2016) <doi:10.18637/jss.v070.i05>,
and MCMC sampling uses the No-U-Turn Sampler described by Hoffman and
Gelman (2014) <https://jmlr.org/papers/v15/hoffman14a.html>.
