WebAn Introduction to Robust and Clustered Standard Errors Linear Regression with Non … WebAn alternative approach―two-way cluster-robust standard errors, was introduced to panel regressions in an attempt to fill this gap. Cameron et al. (2011) and Thompson (2011) proposed an extension of one-way cluster-robust standard errors to allow for clustering along two dimensions.
