Singular-Spectrum Analysis Toolkit (SSA)
What is SSA?
The Singular-Spectrum Analysis Toolkit (SSA) is a time series analysis
program. SSA performs detailed spectral analyses and decompositions on
an input time series. The toolkit contains procedures for:
- decomposing time series into trends, quasiperiodic and periodic
oscillations, other significant components, and noise,
- reconstructing the contributions of selected componetns of the
times series, and
- estimating spectral properties of the times series or any of its
components by modern spectral methods.
Three methods of spectral-analysis are provided: Blackman-Tukey
correlogram estimation, Multi-Taper Method (MTM), and Maximum-Entropy
Method.
How to Use
To use the program you will need to add /usr/local/ssa/bin to your
path in .tcshrc file:
set path=(/usr/local/ssa/bin $path)
Some examples are located in /usr/local/ssa/examples. Some of
the binaries located in /usr/local/ssa/bin can also be run
with a graphical interface. The graphical interface to SSA Toolkit is
a program called: spectra.
