WebOct 23, 2024 · In STATA clustered standard errors are obtained by adding the option cluster(variable_name) to your regression, where variable_name specifies the variable … WebOct 9, 2015 · There's no formal test that will tell you at which level to cluster. If you think that the regressors or the errors are likely to be uncorrelated within a potential group, then there is no need to cluster within that group. Larger and fewer clusters have less bias, but they have more variability, so there's a kind of a trade-off there.

WebNov 16, 2024 · This method is significantly helpful when the theoretical distribution of the test statistic is unknown. In Stata, you can use the bootstrap command or the vce (bootstrap) option (available for many estimation commands) to bootstrap the standard errors of the parameter estimates. WebThe vce option: changing standard error reports for quirky data The vce () option causes Stata to change the way standard error is calculated. The vce option has three major types of variance estimators: likelihood-based, replication-based and sandwich estimators.
