Question

我有以下类型的数据（其他变量可以完全随机）：

Name  Member  Other variables
 AAA    0
 AAA    0
 AAA    1
 BBB    0
 BBB    0
 CCC    1

请注意，1可以出现在任何位置的一组重复项中，但每个重复项只会出现一个。

我想删除重复内容如下：

如果成员为1，则无需担心，不会出现重复问题（例如CCC）。
如果所有重复的成员都是0，那也可以（例如，BBB）
如果成员有1而其余成员0，那么该副本集的所有其他行都需要等于1。

我尝试过使用duplicates，使用_N，_n等自定义例程，但由于我不知道如何循环使用一次重复一组（也查看了foreach等）。

最终结果应如下所示：

Name  Member  Other variables
 AAA    1
 AAA    1
 AAA    1
 BBB    0
 BBB    0
 CCC    1

我想到的一件事是，如果我能够以某种方式一次使用一个组，我可以将max()应用于每个重复块的成员列，这将产生我想要的。但问题是，我不知道如何一次与一个小组合作。

加成：

如果我还可以在此更改后消除重复并到达下面的设置，那将是一个很好的奖励。但我认为，一旦上述步骤明确，我就知道如何到达那里。

Name  Member  Other variables
AAA    1
BBB    0
CCC    1

或

clear

input str3 Name  Member
AAA 0
AAA 0
AAA 1
BBB 0
BBB 0
CCC 1
end

bysort Name (Member) : egen Wanted1 = max(Member)

两者都能产生所需的输出：

bysort Name (Member) : generate Wanted2 = Member[_N]

请注意，在任何（子）观测集中，list, sepby(Name) +-----------------------------------+ | Name Member Wanted1 Wanted2 | |-----------------------------------| 1. | AAA 0 1 1 | 2. | AAA 0 1 1 | 3. | AAA 1 1 1 | |-----------------------------------| 4. | BBB 0 0 0 | 5. | BBB 0 0 0 | |-----------------------------------| 6. | CCC 1 1 1 | +-----------------------------------+从_n到1。因此， _N总是索引 last 观察。

奖金：

_N

使用重复集并重置组
