英文:
Standardize multiple variables
问题
需要使用Stata标准化文本文件中的数百个变量，其中第一列是id，随后的列是varlist。转换后，需要将只包含id（第一列）和所有标准化值的新文件导出到我的目录。
英文:
I need to standardize hundreds of variables in a text file that has id as first column and varlist in subsequent columns using Stata. After conversion, I need to export the new file that only has id (first column) and all standardized values to my directory.

ds id, not
foreach v in r(varlist)' { tempvar work egen work' = std(v') drop v'
rename work' v'
}
查看 `help egen` 以确认其标准化方法是否与你的匹配
