r-cran-lava binary package in Ubuntu Bionic amd64

 A general implementation of Structural Equation Models
 with latent variables (MLE, 2SLS, and composite likelihood
 estimators) with both continuous, censored, and ordinal
 outcomes (Holst and Budtz-Joergensen (2013)
 <doi:10.1007/s00180-012-0344-y>). The package also provides
 methods for graph exploration (d-separation, back-door criterion),
 simulation of general non-linear latent variable models, and
 estimation of influence functions for a broad range of statistical
 models.
