Time Series Forecasting with ARIMA Models

Raw historical data holds valuable patterns that can help you predict the future, but unlocking these insights requires a structured approach. Understanding how to model time-dependent data is a crucial skill for analysts, developers, and researchers alike. In this text-only course, you will learn the foundational concepts and practical applications of ARIMA modeling. You will transition from understanding basic statistical properties to confidently building, testing, and deploying forecasts over various time horizons. What you'll learn: - Understand the core components of time series data, including stationarity, seasonality, and trend. - Analyze Autoregressive (AR) and Moving Average (MA) processes to identify underlying patterns. - Configure and fit ARIMA and seasonal (SARIMA) models using modern programming libraries. - Evaluate forecasting performance using key metrics and residual diagnostics. - Apply automated model selection techniques to find optimal parameters efficiently. - Forecast future data points across short-term and long-term horizons. The curriculum begins with essential statistical concepts and data preparation techniques, then moves step-by-step through model identification, fitting, and validation using clear, written explanations and code examples. Designed for beginners in data analysis, this course requires no advanced mathematics background and starts with key terminology before moving to practical implementation.
