This module offers a comprehensive exploration of ARMA (Auto Regressive Moving Average) processes, equipping students with the ability to dissect and comprehend the mechanics of ARMA models, including terminology and mathematical foundations like the backward shift operator. Through hands-on experience, students will learn to classify ARMA processes based on causality and invertibility, estimate key statistical properties of stationary time series such as the sample mean, autocovariance, and autocorrelation using R, and employ visual tools to determine the order of MA processes. This module also provides an introduction to forecasting, where students apply prediction operators to achieve optimal forecasts for stationary processes, rounding out their foundational understanding of time series analysis.

This module introduces students to ARIMA and SARIMA modeling techniques, essential for analyzing non-stationary and seasonal time series data. In the first lesson, students will learn to define ARIMA processes, use the Dickey-Fuller test to determine the need for differencing, and fit ARIMA models using R, incorporating the concept of exponential smoothing. The second lesson extends these skills to SARIMA models, focusing on identifying seasonality and fitting these models to capture seasonal patterns in data, providing a comprehensive toolkit for sophisticated time series analysis.

This module equips students with advanced forecasting techniques beyond one-step-ahead predictions, focusing on ARMA, ARIMA, and SARIMA processes using R. In the initial lesson, learners will explore methodologies for generating multi-step forecasts with these models. The subsequent lesson dives into exponential smoothing, teaching students to handle models with additive errors, trends, and seasonality, and how to effectively use R's HoltWinters and forecast functions to fit and interpret time series forecasts, thus providing a thorough grounding in dynamic forecasting methods.
