WebMay 7, 2024 · Clustered standard errors employ estimates of the error covariances within the cluster and ignore the remaining covariances. Since the only variance within the cluster is time series variance, this procedure corrects the standard errors for serial correlation, but the procedure can fail in several circumstances. WebUse clustered standard errors. E.g. if you've got kids in classrooms, and want to know their mean score on a test, you can use clustered standard errors. Is the cluster something you're interested in or want to remove? E.g. if you've got kids in classrooms, and you want to make one classroom the reference, use fixed effects.
