I am attempting to -merge- on only one variable (placefip), and 67% of memory is free before I attempt the -merge- (i.e., while the "master" dataset is loaded). The "using dataset is small, and I've got the memory set quite high (900m). So, I can't understand why I am...
在Stata中使用merge命令时遇到错误“factor-variable and time-series operators not allowed”通常意味着在合并过程中使用了不被允许的变量类型或操作符。这里有几个步骤可以帮助你解决这个问题: 理解错误信息: “factor-variable and time-series operators not allowed”意味着在合并操作中,你可能使用了因子变量(facto...

另外,Stata字符串操作函数有哪些? 楼主,你可以试一下 regexm indexnot()、strpos() lookfor -- Search for string in variable names and labels 面板数据中,根据样本(id)和观测期(t)生成一个新变量number,其内容是每个样本的观测期个数, inp id t 1 1991 1 1992 1 1993 2 1991 2 1992 3 19...

one per year (2000-2019), with lots of health infotmation. The problem comes when those data change the number of columns, and the class of many variables whith time (numeric to character or viceversa for the same variable). The expected result is to have only one data frame for the ...

variable (or variables) that serve id variables, in this case id. Next is the argument using this tells Stata that we are done listing the id variables, and that what follows are the dataset(s) to be merged. The names are listed, with only spaces (no commas, etc.) between them. (...
For example, if data set 1 and 2 both contain a variable called "date" (in addition to the common variables on which you are merging), merging those two data sets will sometimes make your results look odd due to how Stata handles what to do with that variable. Best, Nick On Jun 1,...
