+    """Latent Variable Models
+
+    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>). Mixture latent variable models and
+    non-linear latent variable models (Holst and Budtz-Joergensen (2019)
+    <doi:10.1093/biostatistics/kxy082>). 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."""
