在 Stata 中转置数据变量名称

Question

你好，我想使用美国国家科学基金会数据集，但原始 excel 文件变量名没有正确转置数据。有没有人有关于如何转置数据集以使其适合用于分析的 stata 格式的示例代码。这是原始 excel 文件，因此您可以了解问题。

*已编辑以添加导入视图

记住 Nick 关于 SO 的本质的恰当观点，我确实有一些示例代码可能对您有所帮助。不知道你所说的“转置”是什么意思，我无法给出确切的答案，但你可以根据你的目的调整下面的 reshape 命令。

导入并查看

构建数据

// Create supercategories
    
    * level = Column A if column A contains the word level (ignoring case)
    gen level = word(A,1) if ustrregexm(A, "level", 1), before(A)
    
    * demographic = Column A if next ob in column A contains the word all fields (ignoring case)
    gen demographic = A if ustrregexm(A[_n+1], "all fields", 1), before(A)
    
    * fill down demographic and level, and drop blank rows
    foreach v of varlist level demographic {
        replace `v' = `v'[_n-1] if missing(`v')
    }
    drop if mi(demographic) | demographic == A | regexm(A, level)
    
// rename variables 

    * rename A
    rename A field
    
    * rename count columns
    local list "B C D E F" 
    local year = 2000
    rename (`list') (all_`year' female_`year' male_`year' perc_female_`year' perc_male_`year' )
    
    local list "G H I J K" 
    local year = 2017
    rename (`list') (all_`year' female_`year' male_`year' perc_female_`year' perc_male_`year' )
    
    * destring 
    destring *_2000 *_2017, replace

整形为长

    * reshape long
    drop perc*
    reshape long all_ male_ female_, i(level demographic field) j(year)
    
    rename *_ degrees*
    reshape long degrees,  i(level demographic field year) j(gender) string

一个示例，说明如何按字段重塑宽度

    * test reshape wide by field + ensure the variable name is less than 32 characters post reshape 
    replace field = lower(strtoname(field))
    replace field = substr(field, 1, 32 - strlen("degrees") - 1) 
    reshape wide degrees, i(level demographic year gender) j(field) string
