%description
Combines Latent Dirichlet Allocation (LDA) and Bayesian multinomial time
series methods in a two-stage analysis to quantify dynamics in
high-dimensional temporal data. LDA decomposes multivariate data into
lower-dimension latent groupings, whose relative proportions are modeled
using generalized Bayesian time series models that include abrupt
changepoints and smooth dynamics. The methods are described in Blei et al.
