%description
Time series analysis tool using linear layered stochastic differential
equations. The package allows for multiple time series with correlative
and/or causal links between them. Unmeasured causal processes are allowed
to affect the measured processes in a layered structure, hence the name of
the package. In case of causal feedback loops, the matrix operations
(including eigenvalue decompositions) allows for complex numbers. In this
case, cyclic behavior can be expected. Details can be found in Reitan and
Liow (2019)<doi:10.1111/2041-210X.13299>.
