%description
Implement some models for correlation/covariance matrices including two
approaches to model correlation matrices from a graphical structure. One
use latent parent variables as proposed in Sterrantino et. al. (2024)
<doi:10.1007/s10260-025-00788-y>. The other uses a graph to specify
conditional relations between the variables. The graphical structure makes
correlation matrices interpretable and avoids the quadratic increase of
parameters as a function of the dimension. In the first approach a natural
sequence of simpler models along with a complexity penalization is used.
The second penalizes deviations from a base model. These can be used as
prior for model parameters, considering C code through the 'cgeneric'
interface for the 'INLA' package (<https://www.r-inla.org>). This allows
one to use these models as building blocks combined and to other latent
Gaussian models in order to build complex data models.
