Except these researches on EV in specific context, most researches either ignore the EV problem or take it subjectively. So in this paper we provide a formal and general reflection on the EV problem and propose a simple and generally applicable measure that evaluates external validity for RCTs.</span></span></span><span lang="EN-US" style="font-family: "Times New Roman", serif;"><o:p></o:p></span></p> |
