The article discusses a Macintosh computer program called AnalySeries, which is available for free on the internet and can perform various time-series analysis procedures. Originally designed for paleoclimatic time series, the program is useful for a wide range of Earth sciences. It features a graphical user interface, making it accessible to users unfamiliar with computer calculations. The program includes tools for stratigraphic correlation, age-model development, interpolation, integral sampling, smoothing, filtering, and fitting of time series. It also provides spectral analysis tools such as the Blackman-Tukey, maximum entropy, multivariate methods, and singular spectrum analysis. Data input and output are easy, and results are displayed graphically. AnalySeries is available at two locations: one in Europe and one in the United States. The authors, Didier Paillard, Laurent Labeyrie, and Pascal Yiou, highlight its utility and provide contact information for further inquiries.The article discusses a Macintosh computer program called AnalySeries, which is available for free on the internet and can perform various time-series analysis procedures.
