FindGraph is comprehensive, feature-rich graph editor, as well as a curve-fitting and digitizing tool for engineers, scientists and graduate students. Discover the model that best describes your data.



$99.50 - GistaT Group

The program is based on the model-free method of time series analysis Caterpillar-SSA (Singular Spectrum Analysis). It allows identification, analysis and forecast of the time series structure. The program can be applied to multivariate analysis.



 
Analysis of time series with missing values.

CatMV
$49.00 - GistaT Group

The CatMV program is a realization of the "Caterpillar"-SSA method for analysis of time series, which may contain missing values. The implemented algorithms result in extraction of additive components of time series such as trends and periodic components, with simultaneous filling in the missing data (if any). The program is able to perform forecasting if to add missing values after the last point of the time series.
