CATS is a system for storing many timeseries with different time bases including yearly, monthly, weekly, daily and many more. It comes with hundreds of collected time series from around the world, including both scientific and market data such as climate, astronomical, geophysical, economic, commodities, prices, and much more.

CATS can analyse series and determine cycles periods and phases precisely, and has many functions for manipulating data such as arithmetic, logs and transformations. It also includes multivariate techniques like correlation, regression, factor analysis and other tools that are useful for model building for economics, climate and in general studying the causal pathways by which cycles are transmitted.
