This video shows how to use kSpectra for SSA prediction of noisy and short time series. It follows example included with the demo version. Cross-validation is demonstrated to choose optimum number of SSA components for prediction, and to provide estimates of the forecast skill. Editing of multiple plots is shown, including browsing, in/out zooming and cropping.

SSA Prediction
This video will show how kSpectra can be used to identify quasi-periodic oscillatory mode embedded in short sample of red noise with large amplitude. It follows Small Signal example included with the demo version. Different spectral estimation tools are demonstrated, as well as editing of plots.

Basic Demo
This video covers different spectral estimation tools, filtering of noise, as well as Data I/O, Utilities and plotting, by using Climate example included with the demo version.
This video covers how to apply SSA to multivariate data with gaps, following example included with the demo version. Cross-validation is used to find optimum number of SSA components to fill-in the missing values with the “smooth” component, and to provide estimates of the reconstruction error. Editing of multiple plots with the help of Plots Gallery is demonstrated.
