WebMay 13, 2024 · In mixed models, we obtain cluster-specific effects in addition to those for standard coefficients of our regression model. The former are called random effects, while the latter are typically referred to as fixed effects or population-average effects. In other circumstances, we could ignore the clustering, and run a basic regression model. WebMay 29, 2024 · Note, -robust- handles uncertainty differently depending upon whether you're estimating your model using -reg- or -xtreg, fe-.
