ABS Training: Understanding Time Series


This course gives participants a detailed understanding of what a time series is, what the process of seasonal adjustment is, how seasonal adjustment is approached in the ABS, what the issues and problems are which may arise during seasonal adjustment and how to address these. It includes the more complex time series adjustments such as trading day and Easter corrections.
