%description
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 (100+) 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,
doubly constrained RR-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.
