In addition, reinstalling the same package from SSC will predictably produce the same result. As I write, the version of -ghansen- on SSC is precisely the one that caused you problems. The author, Jorge, has yet to fix it. Muhammad: You either wait for it to be fixed or fix it by hand on your own machine, as I did. Sorry if you thought that I had fixed the package on SSC, but that's not for me to do, as I am not the author. . mata mata clear flushes any Mata code in memory.
