Time series analysis is a theory and method to establish mathematical model by curve fitting and parameter estimation based on time series data obtained from systematic observation. It is usually carried out by curve fitting and parameter estimation methods (such as nonlinear least square method). Time series analysis is often used in macro-control of national economy, regional comprehensive development planning, enterprise management, market potential prediction, meteorological forecast, Hydrological Prediction, earthquake precursor prediction, crop pest and disease disaster prediction, environmental pollution control, ecological balance, astronomy and oceanography.
