   Dummy coding allows us to turn categories into something a regression can treat as having a high (1) and low (0) score. Any binary variable can be thought of as having directionality, because if it is higher, it is category 1, but if it is lower, it is category 0.

   What is a dummy variable in regression analysis?

   • In regression analysis, a dummy variable is a regressor that can take only two values: either 1 or 0. Dummy variables are typically used to encode categorical features. Suppose that we want to analyze how personal income is affected by: postgraduate education. To do so, we can specify a linear regression model as follows: where:

   What is Dummy coding?

   • Dummy coding is a way of incorporating nominal variables into regression analysis, and the reason why is pretty intuitive once you understand the regression model. Regressions are most commonly known for their use in using continuous variables (for instance, hours spent studying) to predict an outcome value (such as grade point average, or GPA).

   What is a dummy variable x 1 x 2?

   • where b 0, b 1, and b 2 are regression coefficients. X 1 and X 2 are regression coefficients defined as: X 1 = 1, if Republican; X 1 = 0, otherwise. X 2 = 1, if Democrat; X 2 = 0, otherwise. The value of the categorical variable that is not represented explicitly by a dummy variable is called the reference group.

   How many dummy variables can a categorical variable create?

   • The number of dummy variables we must create is equal to k-1 where k is the number of different values that the categorical variable can take on. The following examples illustrate how to create dummy variables for different datasets.
