What is a Time Series?
A time series is a sequence of data points collected or recorded at successive points in
time, often at uniform intervals. Time series data is prevalent across numerous disciplines,
including finance (stock prices), economics (GDP, unemployment rates), environmental
science (temperature readings), and engineering (sensor data).
Characteristics of Time Series Data
Trend: The long-term progression or movement in the data over time.
Seasonality: Regular, periodic fluctuations that occur at specific intervals (e.g.,
monthly, quarterly).
Cyclicality: Fluctuations that are not of fixed period, often associated with
economic or business cycles.
Irregularity: Random or residual variations not explained by the other
components.
Understanding these components helps in modeling and forecasting future data points
effectively. ---
Fundamentals of Time Series Analysis
Time series analysis involves methods for analyzing the data to extract meaningful
statistics and identify underlying patterns. It typically includes decomposition, modeling,
and forecasting.
