%description
Implementation of dynamic principal component analysis (DPCA), simulation
of VAR and VMA processes and frequency domain tools. These frequency
domain methods for dimensionality reduction of multivariate time series
were introduced by David Brillinger in his book Time Series (1974). We
follow implementation guidelines as described in Hormann, Kidzinski and
Hallin (2016), Dynamic Functional Principal Component
<doi:10.1111/rssb.12076>.
