quadform

<p>We compute the quadratic form of a vector and a matrix in an efficient
manner. Let <code>x</code> be a real vector of length <code>p</code>, and let <code>A</code> be
a p x p real matrix. Then, we compute the quadratic form \(q = x' A x\).</p>

A collection of sparse and regularized discriminant analysis
methods intended for small-sample, high-dimensional data sets. The package
features the High-Dimensional Regularized Discriminant Analysis classifier
from Ramey et al. (2017) <arXiv:1602.01182>. Other classifiers include
those from Dudoit et al. (2002) <doi:10.1198/016214502753479248>, Pang et
al. (2009) <doi:10.1111/j.1541-0420.2009.01200.x>, and Tong et al. (2012)
<doi:10.1093/bioinformatics/btr690>.
