Description: Fits and analyzes linear latent non-Gaussian models for
    temporal, spatial, and space-time data. The package provides model
    components for autoregressive and Ornstein-Uhlenbeck processes, random
    walks, Matern fields based on stochastic partial differential equations,
    separable and non-separable space-time models, graph-based Matern models,
    bivariate type-G fields, and user-defined sparse operators. Latent fields
    and observation models can use Gaussian and non-Gaussian noise
    distributions, including normal inverse Gaussian, generalized asymmetric
    Laplace, and skew-t distributions. Functions are included for simulation,
    likelihood-based estimation, prediction, cross-validation, convergence
    diagnostics, stochastic gradient optimization, batch-means confidence
    intervals, and posterior-like sampling. The modeling framework is described
    in Bolin, Jin, Simas and Wallin (2026) "A Unified and Computationally
    Efficient Non-Gaussian Statistical Modeling Framework"
    <doi:10.48550/arXiv.2602.23987>.
