   Feb 2, 2021 · Dummy Variables: Numeric variables used in regression analysis to represent categorical data that can only take on one of two values: zero or one. 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.

   How many dummy variables can a regression test take?

   • Their range of values is small; they can take on only two quantitative values. As a practical matter, regression results are easiest to interpret when dummy variables are limited to two specific values, 1 or 0. Typically, 1 represents the presence of a qualitative attribute, and 0 represents the absence.

   What is a regression coefficient on a dummy variable?

   • In general, the regression coefficient on a dummy variable gives us the average increase in observed when the dummy is equal to 1 (with respect to the base case in which the dummy is equal to 0). Let us continue with the previous example, to see how a dummy variable looks like when the data is gathered in a matrix or table.
