。谢谢各位同行!真心感谢!
(2) Your data have clusters and thus IID violations. This requires the use of cluster-corrected standard errors or possibly even HLM. Since most regression packages allow for cluster-corrected SEs only on one level, please show the ICC(1) values for each possible area of clustering (in particular, industry, region).
(4) As a robustness test, please include in the paper results using a Tobit regression specification. Again, this will require cluster-corrected SEs.
