This course discusses the fundamentals of modeling time series data. The course focuses on the applied use of the three main model types used to analyze univariate time series: exponential smoothing, autoregressive integrated moving average with exogenous variables (ARIMAX), and unobserved components (UCM).

Aprenda a

• Create time series data.
• Accommodate trend, as well as seasonal and event-related variation, in time series models.
• Diagnose, fit, and interpret exponential smoothing models, ARIMAX models, and unobserved components models.
• Identify relative strengths and weaknesses of the three model types.

A quién va dirigido

Analysts with a quantitative background as well as non-statistical analysts and domain experts who would like to augment their time series modeling proficiency
