That is why manually adding dummy variables doesn't work (requires 400 Gb) 1) Is there any way to do it in SAS? I can use "proc glm" but it can't do clustering on the other hand "proc surveyreg" can do clustering but requires dummy variables. 2) An alternative solution is to export data to txt and upload it to Stata. tops physio summertownWebbTo get White standard errors in SAS, you can do any of the following: 1. Run proc reg with the acov option. Like so: proc reg data=mydata; model y = x / acov; run; This prints the robust covariance matrix, but reports the usual OLS standard errors and t-stats. To get robust t-stats, save the estimates and the robust covariance matrix. tops phuketWebb18 jan. 2008 · Appendix B gives the command syntax for Proc Glimmix in SAS (for the SRS variance estimate) and for Proc SurveyReg in SAS to calculate the variance estimates under random cluster sampling (GEEs) and stratified cluster sampling.
