Trend, Seasonality, and Cycles The primary structure of any sequence can be described by three main features. Unlike standard data analysis where observations are assumed to be independent, this discipline recognizes that the order and timing of data points create a unique context that must be preserved.

In finance, it is used for algorithmic trading, risk management, and predicting market volatility. Methodologies and Techniques The field employs a diverse toolkit to model these complexities, ranging from classical statistical approaches to modern machine learning.
By acknowledging that today’s observation is often influenced by yesterday’s, it moves beyond simple averages to model the inherent dynamics of change. These models often require feature engineering, such as creating lag variables or rolling statistics.
