Abstract
Autoregressive modelling provides a powerful and flexible parametric approach to modelling
uni- or multi-variate time-series data. AR models have mathematical links to linear time-
invariant systems, digital filters and Fourier based frequency analyses. As such, a wide range
of time-domain and frequency-domain metrics can be readily derived from the fitted au-
toregressive parameters. These approaches are fundamental in a wide range of science and
engineering fields and still undergoing active development. SAILS (Spectral Analysis in Linear
Systems) is a python package which implements such methods and provides a basis for both
the straightforward fitting of AR models as well as exploration and development of newer
methods, such as the decomposition of autoregressive parameters into eigenmodes.
