%description
Implements approximate Bayesian inference for Structural Equation Models
(SEM) using a custom adaptation of the Integrated Nested Laplace
Approximation (Rue et al., 2009) <doi:10.1111/j.1467-9868.2008.00700.x> as
described in Jamil and Rue (2026a) <doi:10.48550/arXiv.2603.25690>.
Provides a computationally efficient alternative to Markov Chain Monte
Carlo (MCMC) for Bayesian estimation, allowing users to fit latent
variable models using the 'lavaan' syntax. See also the companion paper on
implementation and workflows, Jamil and Rue (2026b)
<doi:10.48550/arXiv.2604.00671>.
