Cluster standard errors
WebNov 16, 2024 · When you are using the robust cluster variance estimator, it’s still important for the specification of the model to be reasonable—so that the model has a reasonable interpretation and yields good predictions—even though the robust cluster variance estimator is robust to misspecification and within-cluster correlation. Webcluster either a string vector with the name of the variables that will be used to cluster the standard errors, or a formula - e.g., ~ rhs, with a summation of the variables that will be used to cluster the standard errors replacing the rhs -, or a vector, matrix, or data.frame with the clustering data. type string with either HC0, HC1, HC2 ...
