The Poisson lognormal model and variants can be used for a variety of multivariate problems when count data are at play (including PCA or LDA for count data, network inference). This package implements efficient variational algorithms to fit such models accompanied with a set of functions for visualization and diagnostic.

and the associated methods for manipulation.

The Poisson PCA and the associated variational inference is fully explained in Chiquet el al (2018), see reference below.
