Webb3 apr. 2024 · For fixed effects models, including dummies (e.g., sector dummies) in the estimation command has the same effect as absorbing the dummies. Therefore, you can be able to suppress the output of the dummy variables by absorbing them. However, this is not the case for random effects models.
