+     "BANDITS is a Bayesian hierarchical model for detecting differential
+splicing of genes and transcripts, via @dfn{DTU} (differential transcript
+usage), between two or more conditions.  The method uses a Bayesian
+hierarchical framework, which allows for sample specific proportions in a
+Dirichlet-Multinomial model, and samples the allocation of fragments to the
+transcripts.  Parameters are inferred via @dfn{MCMC} (Markov chain Monte
+Carlo) techniques and a DTU test is performed via a multivariate Wald test on
+the posterior densities for the average relative abundance of transcripts.")
