Time Series Forecasting with ARIMA Models

Predicting future trends from historical data is a critical skill in data science, finance, and business operations. Understanding how to model time-dependent data is the first step to making accurate, data-driven forecasts. This text-only course guides you through the foundational concepts and practical application of ARIMA models, helping you move from raw sequential data to reliable forecasts. By completing this course, you will understand how to analyze historical patterns, prepare data for modeling, and construct forecasts with confidence. What you'll learn: - Understand the core components of ARIMA, including autoregression, differencing, and moving averages. - Analyze time series data for stationarity and apply transformations to stabilize variance. - Configure model parameters using autocorrelation and partial autocorrelation analysis. - Evaluate forecasting performance using modern statistical metrics and residual diagnostics. - Apply automated ARIMA selection tools using modern Python libraries to streamline your forecasting workflow. You will begin by exploring essential time series terminology and foundational mathematical concepts before walking through step-by-step model configuration and diagnostic testing. The course concludes with practical written exercises designed to reinforce your understanding of forecasting workflows. This course is designed for beginner data analysts, programmers, and researchers who want to learn time series forecasting from the ground up. No prior experience with forecasting models is required.
