Poisson Lognormal Models
The Poisson-lognormal model and variants (Chiquet,
Mariadassou and Robin, 2021 ) can be
used for a variety of multivariate problems when count data are at
play, including principal component analysis for count data,
discriminant analysis, model-based clustering and network inference.
Implements variational algorithms to fit such models accompanied with
a set of functions for visualization and diagnostic.
