WebCluster robust standard errors (clustered on ID) would be the correct way. Cameron and Trivedi (2009) "Microeconometrics Using Stata" describe this in more detail. To use the Hausman test FE v.s. RE you can substitute RE with OLS. Both RE and OLS rely on the same assumptions for consistency, so if your test rejects RE it will likely reject OLS ... WebMar 26, 2024 · The Akaike information criterion is a mathematical test used to evaluate how well a model fits the data it is meant to describe. It penalizes models which use more independent variables (parameters) as a way to avoid over-fitting. AIC is most often used to compare the relative goodness-of-fit among different models under consideration and to ... scottsdale dave and busters
