%description
Set of tools to find coherent patterns in gene expression (microarray)
data using a Bayesian Sparse Latent Factor Model (SLFM)
<DOI:10.1007/978-3-319-12454-4_15>. Considerable effort has been put to
build a fast and memory efficient package, which makes this proposal an
interesting and computationally convenient alternative to study patterns
of gene expressions exhibited in matrices. The package contains the
implementation of two versions of the model based on different mixture
priors for the loadings: one relies on a degenerate component at zero and
the other uses a small variance normal distribution for the spike part of
the mixture.
