%description
Implements a flexible, versatile, and computationally tractable model for
density regression based on a single-weights dependent Dirichlet process
mixture of normal distributions model for univariate continuous responses.
The model assumes an additive structure for the mean of each mixture
component and the effects of continuous covariates are captured through
smooth nonlinear functions. The key components of our modelling approach
are penalised B-splines and their bivariate tensor product extension. The
proposed method can also easily deal with parametric effects of
categorical covariates, linear effects of continuous covariates,
interactions between categorical and/or continuous covariates, varying
coefficient terms, and random effects. Please see Rodriguez-Alvarez,
Inacio et al. (2025) for more details.
