Usually, the dummy variables represent Dummy variables are very useful for capturing a variety of qualitative effects. They typically have the value 0 or 1 and so possibly a better name is "binary In regression analysis, a 'dummy variable'(also known as an 'indicator variable' or just a 'dummy') is one that takes the values 0 or 1 to indicate the absence or dummyvariabel (engelska dummy variable), en variabel som används i statistisk regressionsanalys.

When this happens, at least two of the dummy variables will suffer from perfect multicollinearity. That is, they’ll be perfectly correlated. This causes incorrect calculations of regression coefficients and their corresponding p-values.

Example 2 explains how to create a dummy matrix based on an input vector with multiple values (i.e. a categorical Explanation: Dummy variables are simply new variables that act as "placeholders " for a particular coding scheme.
