%description
Lightweight utilities to estimate autoregressive (AR) and autoregressive
moving average (ARMA) noise models from residuals and apply matched
generalized least squares to whiten functional magnetic resonance imaging
(fMRI) design and data matrices. The ARMA estimator follows a classic 1982
approach <doi:10.1093/biomet/69.1.81>, and a restricted AR family mirrors
workflows described by Cox (2012) <doi:10.1016/j.neuroimage.2011.08.056>.
