Sas proc reg clustered standard errors
WebbHowever, researchers rarely explain which estimate of two-way clustered standard errors they use, though they may all call their standard errors “two-way clustered standard errors”. My note explains the finite sample adjustment provided in SAS and STATA and discussed several common mistakes a user can easily make.

We can easily generate a percentile confidence interval in SAS using proc univariate after creating some macro variables for the percentiles of interest and using them in the output ...
