Abstract

In this chapter, we use 0–1 indicator or “dummy” variables to incorporate shocks, structural shifts or segment differences into models. In cross-sectional data, indicators allow us to compare response across groups or segments. In time-series data, indicators allow us to modify responses to account for external shocks or structural shifts. Indicators also offer one option to account for seasonality or cyclicality in time series.
