如何將包含多個變量的列轉換爲單獨的變量列

給定一個時間，我有九個不同主題的每個活動值。我想實現這一主題列轉化爲9個新的變量，例如，我有以下結構：

時間，活動，主題1，主題2，...，主題9

在哪裏主題變量包含值的相應條目。

所以在最後我希望有時間的每一個點，8個活動和

Time | ACTIVITY | Subject1 | Subject2 | ... | Subject9 
    -----| ---------|----------|----------|-----|---------- 
    1995 | A  | example | example |  | example 
    1995 | F  | example | example |  | example 
    1995 | K  | example | example |  | example 
    1995 | J  | example | example |  | example

...

我已經嘗試過了reshape命令， reshape wide ACTIVITY, i(Value) j(Subject) string但我懷疑reshape isn'在這裏輸入正確的命令來獲得我想要的結果。

屏幕截圖的使用非常有限：讀者在屏幕截圖和問題之間來回切換，無法複製並粘貼到他們的Stata中。請發佈一個明確的數據示例。 'dataex'（SSC;使用'ssc inst dataex'安裝）將有所幫助。我們不能評論你的'reshape'命令，因爲你沒有給出代碼。請研究http://stackoverflow.com/help/mcve –

感謝您的編輯。這些數據的'reshape'命令是錯誤的。請參閱下面的答案。 –

在Stata中，列是矩陣的列。你所稱的列是變量。

你的屏幕截圖顯示了以下幾個問題：

你Time變量和Value變量是字符串。這看起來不對。這些變量中可能存在某些垃圾。也許標題已被複制到數據中。 list Time if missing(real(Time))是一種會顯示非數字值的命令。
您的Subject變量顯示尾隨空格。如果不一致，可能會導致問題。
您的Subject變量的不同值不能是給定嵌入空格的變量名稱的一部分。所以，我們需要一些額外的工作。

此代碼生成一個玩具的例子，並展示一些技巧。與你的猜測相反，reshape是首選命令。

set obs 6 
gen location = "AUS" 
gen time = 1995 
gen subject = cond(mod(_n, 2), "Fooling around ", " Wasting time") 
gen activity = word("A F K", ceil(_n/2)) 
gen value = _n 
replace subject = trim(subject) 
list

egen group = group(subject), label 
su group, meanonly 
local gmax = r(max) 
forval g = 1/`gmax' { 
    local lbl`g' "`: label (group) `g''" 
} 
drop subject 

reshape wide value, i(location time activity) j(group) 

forval g = 1/`gmax' { 
    label var value`g' "`lbl`g''" 
}
