%description
Different estimators are provided to solve the blind source separation
problem for multivariate time series with stochastic volatility and
supervised dimension reduction problem for multivariate time series.
Different functions based on AMUSE and SOBI are also provided for
estimating the dimension of the white noise subspace. The package is fully
described in Nordhausen, Matilainen, Miettinen, Virta and Taskinen (2021)
<doi:10.18637/jss.v098.i15>.
