stata遇到string variable的解决方法 在Stata中,处理字符串变量的方法有很多种。下面是一些常见的方法: 1.使用generate命令创建一个新的变量,并将字符串变量转换为数值变量。例如,假设你有一个字符串变量“string_var”,你可以使用以下命令将其转换为数值变量: ```stata generate numeric_var = real(string_var) `...
针对您的问题“string variables not allowed in varlist; id is a string variable”,以下是我的详细回答: 1. 解释字符串变量在varlist中不允许的原因 在Stata中,某些命令或函数对变量类型有特定要求。varlist通常是指一系列要处理的变量列表,而一些命令,如xtset(用于设定面板数据的面板标识符和时间变量),要求其...
(1)打开stata15.0,不要打开任何数据文件,并提前把需要转化的数据文件放入stata的安装目录下(我的文件名为2013.dta)。 (2)输入命令:unicode analyze 2013.dta (3)输入命令:unicode encoding set gb18030 (4)输入命令:unicode translate "2013.dta", invalid(mark) transutf8 (5)友情提示,第(4)步中有两点需要...
SubjectRe: st: Convert to stata date - stored as a numeric variable DateThu, 12 Sep 2013 07:34:55 +0100 Your date looks like YMD to me which is what to feed to -date()-. If it is really quarterly you need -qofd()- not -mofd()-. ...
does not work I just get missing values. Presumably that is becausemy date variable is not in the order: day - month - year, but ratheryear - month - day. So then do not tell Stata to use the wrong order! Consider: // Begin part 2 of example ...

我正在从Stata转换到R.在Stata中,如果我将因子级别(比如-0和1)标记为(M和F),则0和1将保持不变.此外,在大多数软件(包括Excel和SPSS)中,这是虚拟变量线性回归所必需的. 但是,我注意到R默认因子水平为1,2而不是0,1.我不知道为什么R会这样做,尽管内部(并且正确地)回归假定0和1作为因子变量.我将不胜感激任...
In C++, è possibile ottenere NaN usando la NAN macro o std::numeric_limits<double>::quiet_NaN(). Non usare l'operatore per eseguire il == test per NaN. In C# usare Double.IsNaN() per testare NaN. In C++ usare isnan() per testare NaN. Si applica a ProdottoVersioni WinRT ...
