abstract: Generalized additive (mixed) models, some of their extensions and other
  generalized ridge regression with multiple smoothing parameter estimation by (Restricted)
  Marginal Likelihood, Cross Validation and similar, or using iterated nested Laplace
  approximation for fully Bayesian inference. See Wood (2025) <https://doi.org/10.1146/annurev-statistics-112723-034249>
  for an overview. Includes a gam() function, a wide variety of smoothers, 'JAGS'
  support and distributions beyond the exponential family.
