Visual time series analysis

We introduce a platform which supplies an easy-to-handle, interactive, extendable, and fast analysis tool for time series analysis. In contrast to other software suits like Maple, Matlab, or R, which use a command-line-like interface and where the user has to memorize/look-up the appropriate commands, our application is select-and-click-driven. It allows to derive many different sequences of deviations for a given time series and to visualize them in different ways in order to judge their expressive power and to reuse the procedure found. For many transformations or model-ts, the user may choose between manual and automated parameter selection. The user can dene new transformations and add them to the system. The application contains efficient implementations of advanced and recent techniques for time series analysis including techniques related to extreme value analysis and filtering theory. It has been successfully applied to time series in economics, e.g. reinsurance, and to vibrational stress data for machinery. The software is web-deployed, but runs on the user's machine, allowing to process sensitive data locally without having to send it away. The software can be accessed under http://www.imm.dtu.dk/~paf/TSA/launch.html.
