Bug, leading to crashes in MTM Reconstruction, has been fixed.May 16, 2006: Universal Binary of Toolkit 4.3 for Mac OS X!.Ap: Toolkit 4.4 ( includes SSA gap-filling)!.Febru: New 64-bit bnaries for Linux and Mac OS 10.5 (Intel ) 32-bit binaries for Linux and Mac OS X (Intel) recompiled with Intel compiler.Janu: Updated 64-bit Linux and 64-bit Mac OS.Available on Linux and Mac OS builds.Īlso, beta-version (with limited features, currently mostly M-SSA) of command-line Toolkit utilities are available for Linux and Mac OS choose " CMD for Linux" or " CMD for Mac", respectively, in download options. Janu: Major upgrade of multivariate analysis: Varimax Rotation for M-SSA.October 12, 2016: Instructions on how to run SSA-MTM Toolkit on Windows via Cygiwn and remote X client (courtesy to Andrew Moy, Aug: Updated command-line Toolkit: Gap-filling added.The black peaks are components of the spectrum associated with a periodic signal, and the significance levels relative to the estimated noise background are shown. The next figure shows MTM spectrum for the same data. Outputs include power spectra and significance tests for correlogram and MTM. You can apply these tools at any point in the analysis to a raw time series, or to SSA reconstructions. These are the traditional Blackman-Tukey windowed correlogram, multi-taper method(MTM), and maximum-entropy method(MEM). In addition, the Toolkit includes three kinds of power-spectrum estimation. The next figure shows SSA eigenspectrum for the SOI time series: Ad hoc and Monte Carlo error bars for the SSA eigenspectra are also included. SSA reconstructions of selected components and tests for the presence of trend and oscillatory components are provided. Using a convinient graphical user interface you can perform singular-spectrum analysis on input data. SOI is a climatic index connected with the recurring El NiÑo conditions in the tropical Pacific it is essentially the normalized monthly mean difference in sea-level pressure between Darwin, Australia and Tahiti (Rasmusson et al., 1990). This is the so-called Southern Oscillation Index (SOI). The Singular Spectrum Analysis - MultiTaper Method (SSA-MTM) Toolkit is a software program to analyze short, noisy time series, such as the one below, as well as multivariate data.
