%description
Implements the Normal-Block model, a Gaussian graphical model with a
latent clustering structure for the multivariate analysis of continuous
data. The model clusters variables and, building on the graphical lasso,
infers a network of statistical dependencies between clusters rather than
between individual variables, for known or unknown clusterings, with an
optional zero-inflation extension for data with an excess of exact zeros.
A complementary family clusters variables by their regression response to
covariates rather than by their covariance, sharing one profile per
cluster. See Tous & Chiquet (2026) <doi:10.1016/j.csda.2026.108347> for
the model itself and its variational expectation-maximization estimation
procedure.
