time series analysis

(analysis of data points collected at uniformly-separated times)

Time series analysis is analysis of data representing a function of time, collected at specific points in time that are separated by a uniform interval. Such analysis is used in astronomy and numerous other fields, including signal processing, communications engineering, and weather forecasting. There are many techniques, which can be classified as:

In astronomy, data is often collected at irregular intervals, requiring some variant time series analysis techniques to accommodate that. Intervals involved can be fractions of a second or can be years, e.g., using historical data.
