CaterpillaSSA is a tool for time series analysis and forecasting in different areas of a science. The program is based on SSA (Singular Spectrum Analysis), and you can identify and analyze additive components of the time series (trends, periodicities, noise) without a-priori assumptions and parametric models. Additional modules of the program allow you to analyze and forecast multi-dimensional time series, and to detect change-points in the time series structure. Simplicity of visual control aids, the convenient navigation through the program, a lot of graphic and additional information make the time series processing easier and deeper.
