Poisson Lognormal Models
The Poisson-lognormal model and variants can be used for
a variety of multivariate problems when count data are at play, including
principal component analysis for count data (Chiquet, Mariadassou and Robin,
2018 <10.1214>), discriminant analysis and
network inference (Chiquet, Mariadassou and Robin, 2018 <1806.03120>).
Implements variational algorithms to fit such models accompanied with a set of
functions for visualization and diagnostic.1806.03120>10.1214>
