%description
The sdrt() function is designed for estimating subspaces for Sufficient
Dimension Reduction (SDR) in time series, with a specific focus on the
Time Series Central Mean subspace (TS-CMS). The package employs the
Fourier transformation method proposed by Samadi and De Alwis (2023)
<doi:10.48550/arXiv.2312.02110> and the Nadaraya-Watson kernel smoother
method proposed by Park et al. (2009) <doi:10.1198/jcgs.2009.08076> for
estimating the TS-CMS. The package provides tools for estimating distances
between subspaces and includes functions for selecting model parameters
using the Fourier transformation method.
