Time series analysis

Definition

Time series analysis is a statistical technique used to analyze time-ordered data points to identify trends, patterns, and seasonal variations over time. This method is essential for understanding the behavior of data collected at regular intervals, allowing for forecasting and informed decision-making. By examining historical data, it can uncover insights that enhance network monitoring and contribute to intelligent automation in system management.
