The postestimation commands in SPost13 are named mtable, mchange, mgen, and mlincom. They are much more powerful than the prvalue, prtab, prgen, prchange, and praccum comamnds in SPost9. To install the spost13_ado package, you must uninstall the spost9_ado packages (run: ado uninstall spost9_ado). The spost9_legacy package (run: search spost9_legacy) installs versions of the pr* commands that are compatable with SPost13. If you are trying to reproduce earlier work that used SPost9, however, the safest thing is to uninstall spost13_ado and spost9_legacy, and install spost9_ado. 01Sep2014
