Hello list, I am having troubles getting cem to run (imb works fine). Any code I do with cem returns this error message: . cem invalid syntax r(197); whether I include variables, the treatment variable or not. I installed via ssc: . ssc install cem checking cem consistency and verifying not already installed... all files already exist and are up to date. I am really puzzled as to why, as imb works. I assume there must be a problem with the cem ado file, as shouldn't it return the "valist required" if I only call the command "cem" (without anything)? Any help would be greatly appreciated! I am running Stata 10 (fully updated), Linux-32bit. Would you need any more information than that?
