WebWhen using panel data, however, you may want to consider using two-way clustered standard errors. These will allow you to control for clusters across two dimensions (i.e. firm & time). For more information on when you may like to use two-way clustered standard errors, you can refer to the following papers: Petersen, M. A. (2009). Web“clustered` - One- or two-way clustering. Configuration options are: clusters - Input containing 1 or 2 variables. Clusters should be integer valued, although other types will be coerced to integer values by treating as categorical variables. cluster_entity - Boolean flag indicating to use entity clusters.
