+
+    An implementation of about 6 major classes of statistical regression
+    models. The central algorithm is Fisher scoring and iterative reweighted
+    least squares. At the heart of this package are the vector generalized
+    linear and additive model (VGLM/VGAM) classes. VGLMs can be loosely thought
+    of as multivariate GLMs. VGAMs are data-driven VGLMs that use smoothing.
+    The book "Vector Generalized Linear and Additive Models: With an
+    Implementation in R" (Yee, 2015) <DOI:10.1007/978-1-4939-2818-7> gives
+    details of the statistical framework and the package. Currently only
+    fixed-effects models are implemented. Many (150+) models and distributions
+    are estimated by maximum likelihood estimation (MLE) or penalized MLE. The
+    other classes are RR-VGLMs (reduced-rank VGLMs), quadratic RR-VGLMs,
+    reduced-rank VGAMs, RCIMs (row-column interaction models)---these classes
+    perform constrained and unconstrained quadratic ordination (CQO/UQO) models
+    in ecology, as well as constrained additive ordination (CAO). Hauck-Donner
+    effect detection is implemented. Note that these functions are subject to
+    change; see the NEWS and ChangeLog files for latest changes."""
