Everyone has tasks that they do all the time—create a particular kind of variable, produce a particular table, perform a sequence of statistical steps, compute an RMSE, etc. The possibilities are endless. Stata has thousands of built-in procedures, but you may have tasks that are relatively...

然后,Stata将确保您的程序调用时使用的是一个现有变量的名称,该变量将被存储在名为varlist的本地宏中。(t即使你只有一个变量并在你的语法语句中使用varname,宏名依然是varlis)尝试pnupt nonesuch,Stata会抱错,说“variable nonesuch not found”。 (如果你之前有过编程经验,并且花费大部分时间用于检查输入错误,仅...
