请看看Stata对encode的说明:encode creates a new variable named newvar based on the string variable varname, creating, adding to, or just using (as necessary) the value label newvar or, if specified, name. Do not use encode if varname contains numbers that merely happen to be stored as st...
1、首先使用不同的命令。2、其次optionnotallowed解决，使用不同的参数、不同的数据集。3、最后使用不同的Stata版本。
正确表达模式是两个等号，您检查一下是不是只有一个等号，以下是正确表达式参考：. list if mpg==21 ...

在数据处理中，可能遇到如“invalid varlist (rule)..: quotes do not match”等语法错误，检查代码中符号使用正确。筛选变量时，避免使用“=exp not allowed”错误，修改为“keep if fid_urban ==0”。新设变量时，利用“gen”和“replace”命令。数据清洗后，实证分析部分可稍后进行。CFPS 数据中...
