Lesson 11: Vector Autoregressive Models/ ARCH Models

Printer-friendly versionPrinter-friendly version

Overview:

This week we'll look at two topics - models for periods of volatile variance (ARCH models) and AR models for multivariate time series.

Learning Objectives:

After successfully completing this lesson, you should be able to:

  • Model the variance of a time series
  • Identify and interpret ARCH models
  • Simultaneously model multiple variables in terms of past lags of themselves and one another
