在重塑中保留变量标签

Question

我想在将数据集从长改成宽后保留变量标签。我在输入数据集时遇到问题（我将它们键入 Excel 然后导入）。

clear
set obs 7

input id    a1  a2  a3
"s001"  "John"  23  "Primary"
"s002"  "Mary"  32  "Secondary"
"s002"  "Anna"  23  "Tertiary"
"s003"  "Joseph"    34  "Secondary"
"s003"  "Oganyo"    23  "Primary"
"s004"  "Manyoya"   34  "Tertiary"
"s005"  "Makbuti"   45  "Primary"
end


*======= Label the variables

label var a1 "partners name"
label var a2 "partners age"
label var a3 "partners education"

foreach variable of varlist a*{
    
    local varlabel : variable label `variable'
    di "`varlabel'"

bys id: gen index = _n

renvars a* , postfix(_)


reshape wide a*, i(id) j(index)

label var `variable'* "`varlabel'"

}

Answer 1

这里的代码非常混乱，如果不进行大手术就无法正常工作。

一开始，您的 input 语句未能在需要时声明字符串变量。

set obs 7 与 end 兼容 input。

一个大问题是您正在循环执行包括 reshape 在内的一堆命令，但只有一个 reshape 需要执行。

你保存变量标签的代码需要单独保存。

renvars 来自 Stata Journal (2005)，这里似乎根本不需要。从 Stata 12（2011！）开始，它应该仍然有效，但基本上被 rename.

的扩展所取代

这是我对您应该给出的示例和您需要的代码的最佳猜测。

clear

input str4 id   str7 a1  a2  str9 a3
"s001"  "John"  23  "Primary"
"s002"  "Mary"  32  "Secondary"
"s002"  "Anna"  23  "Tertiary"
"s003"  "Joseph"    34  "Secondary"
"s003"  "Oganyo"    23  "Primary"
"s004"  "Manyoya"   34  "Tertiary"
"s005"  "Makbuti"   45  "Primary"
end

label var a1 "partner's name"
label var a2 "partner's age"
label var a3 "partner's education"

local j = 0 
foreach variable of varlist a* { 
    local ++j 
    local varlabel`j' : variable label `variable'
    di "`varlabel`j''"
} 

bys id: gen index = _n 

reshape wide a*, i(id) j(index)

forval j = 1/3 { 
    foreach v of var a`j'* { 
        label var `v' "`varlabel`j''"
    }
}

list 

describe

这是最后两个命令的输出。

. list

注意：reshape wide 让 Stata 中的大多数事情变得更加困难。

注意：请使用dataex在Stata中创建可重现的数据示例。
