   Feb 2, 2021 · Dummy Variable Trap: When the number of dummy variables created is equal to the number of values the categorical value can take on. This leads to multicollinearity, which causes incorrect calculations of regression coefficients and p-values.

   Definition. The dummy variable trap refers to a scenario in regression analysis where the inclusion of dummy variables for all categories of a categorical variable leads to perfect multicollinearity.

   The Dummy Variable Trap occurs when two or more dummy variables created by one-hot encoding are highly correlated (multi-collinear). This means that one variable can be predicted from the others, making it difficult to interpret predicted coefficient variables in regression models.

   How to avoid a dummy variable trap in multiple linear regression?

   • Thus, when we go to perform multiple linear regression the calculations for the regression coefficients will be incorrect. You only need to remember one rule to avoid the dummy variable trap: If a categorical variable can take on k different values, then you should only create k-1 dummy variables to use in the regression model.

   How to avoid dummy variables in a regression model?

   • You only need to remember one rule to avoid the dummy variable trap: If a categorical variable can take on k different values, then you should only create k-1 dummy variables to use in the regression model. For example, suppose you’d like to convert a categorical variable “school year” into dummy variables.

   How can we avoid the dummy variable trap and multicollinearity?

   • Since the number of dummy variables is one less than the number of values that “school year” can take on, we can avoid the dummy variable trap and the problem of multicollinearity. This tutorial provides an explanation of the dummy variable trap, including a definition and an example.
