The interval-at-minimum scaling assumption means that the difference between any two values in a variable should be meaningful and equal. However, when using a dummy variable (which takes on the values of 0 or 1), this assumption is not necessary because the variable is categorical and not continuous. Therefore, a dummy variable can be used to relax the interval-at-minimum scaling assumption in multiple regression.
