Dummy Variable

Generally, a dummy variable is a placeholder for a variable that will be integrated over, summed over, or marginalized. However, in machine learning, it often describes the individual variables in a one-hot encoding scheme. Thus, dummy or Boolean variables are qualitative variables that can only take the value 0 or 1 to indicate the absence or presence of a specified condition. These “truth” variables are used to sort data into mutually exclusive categories or to trigger off/on commands.
