+regression) using a mixture of regression model and an inverse regression
+strategy.  The methods include the GLLiM model (see Deleforge et al (2015)
+<DOI:10.1007/s11222-014-9461-5>) based on Gaussian mixtures and a robust
+version of GLLiM, named SLLiM (see Perthame et al (2016)
+<DOI:10.1016/j.jmva.2017.09.009>) based on a mixture of Generalized Student
+distributions.  The methods also include BLLiM (see Devijver et al (2017)
+<@code{arXiv:1701.07899>}) which is an extension of GLLiM with a sparse block
+diagonal structure for large covariance matrices (particularly interesting for
+transcriptomic data).")
