Time Series Analysis

Course Description

This graduate-level course, "Time Series Analysis," offered by MITx, is an extensive exploration of time series data and its applications in statistical learning. The course delves into three main areas: Learning Structured Models, Prediction, and Optimal Intervention and Reinforcement Learning. Students will gain a deep understanding of time series analysis, from modeling stochastic dynamic processes to predicting future outcomes and optimizing interventions.

What Students Will Learn
