Preferred term

dummy variables  

Definition

  • A dummy, or indicator, variable is any variable in a regression equation that takes on a finite number of values so that different categories of a nominal variable can be identified. The term dummy simply relates to the fact that the values taken on by such variables (usually values such as 0 and 1) indicate no meaningful measurement but rather the categories of interest.
