| Subject | st: clustering SE xtprobit and xtgee |
| Date | Fri, 24 Feb 2012 09:21:29 +0100 |
Dear Statalists, I'am working on a balanced panel of N=787 firms and T=2 years, where T1=2003 and T2=2006. I would like to cluster (robust) SE at the district-sector level, because I am testing the role of agglomeration forces defined at district-sector level. I have two dependent variable: (i) a dummy variable; (ii) a proportion variable. I would like to run xtprobit/xtlogit for the dummy variable, and xtgee (following Papke and Wooldridge, 2008) for the proportion variable. Could somebody help me? Thanks in advance, Roberto
