使用 SPSS 以编程方式在案例之间复制数据

Question

对于一个学校项目，我发现自己在使用人口普查局当前人口调查的数据。我选择 SPSS 来处理数据，因为在我有限的时间范围内，它似乎是最容易直接使用的软件。一切似乎都很简单，除了一个给我带来麻烦的操作。

对于我的数据集中的每个案例——每个案例代表一个被调查的个体——定义了以下（相关）变量：

• Household ID (HHID) - 每个被调查家庭的唯一编号
• 个人 ID (PID)——家庭中每个人的唯一编号
• 此人的年龄 (AGE)
• 此人是否接受公共健康保险--a 0 或 1 (HASHEALTH)
• 个人父亲的个人ID，如果家庭中存在（如果不存在则为0）（POPNUM）
• 个人母亲的个人 ID，如果家庭中存在（如果不存在则为 0）（MOMNUM）

问题是：我需要将任何给定父母的 KIDHASHEALTH 值设置为 HHID 和 POPNUM 或 MOMNUM 值与当前案例的 HHID 和 PID 匹配的最年轻的人的 HASHEALTH 值——从功能上讲，他们最小的孩子。

到目前为止，我一直无法弄清楚如何使用 SPSS 语法来做到这一点。任何人都可以想出一种方法来完成我正在尝试做的事情，使用语法或其他方式吗？

提前非常感谢。

使用示例数据编辑：

HHID |PID |AGE |POPNUM |MOMNUM |HASHEALTH |KIDHASHEALTH
-----+----+----+-------+-------+----------+------------
1    |1   |45  |0      |0      |0         |0 //KIDHASHEALTH == 0 because
1    |2   |48  |0      |0      |0         |0 //youngest child's HASHEALTH == 0
1    |3   |13  |1      |2      |0         |0
2    |1   |33  |0      |0      |0         |1 // == 1 because youngest child's
2    |2   |28  |0      |0      |0         |1 // HASHEALTH == 1
2    |3   |15  |1      |2      |0         |0
2    |4   |12  |1      |2      |1         |0

以下代码仅在您的小数据 sn-p 上进行了测试。因此，不能保证所有数据的特殊性。代码假设 AGE 是整数。

*Let's add small fractional noise to those children AGE who HASHEALTH=1.
*In order to insert the info about health right into the age number. 
if hashealth age= age+rv.unif(-.1,+.1).

*Turn to fathers. Combine POPNUM and PID numbers in one column.
compute parent= popnum. /*Copy POPNUM as a new var PARENT.
if parent=0 parent= pid. /*and if the case is not a child, fill there PID.
*Now a father and his children have the same code in PARENT
*and so we can propagate the minimal age in that group (which is the age of the
*youngest child, provided the man has children) to all cases of the group,
*including the father.
aggregate /outfile= * mode= addvari
          /break= hhid parent /*breaking is done also by household, of course
          /youngage1= min(age). /*The variable showing that minimal age.
*Turn to mothers and do the same thing.
compute parent= momnum.
if parent=0 parent= pid.
aggregate /outfile= * mode= addvari
          /break= hhid parent
          /youngage2= min(age). /*The variable showing that minimal age.
*Take the minimal value from the two passes.
compute youngage= min(youngage1,youngage2).

*Compute binary KIDHASHEALTH variable.
*Remember that YOUNGAGE is not integer if that child has HASHEALTH=1.
compute kidhashealth= 0.
if popnum=0 and momnum=0 /*if we deal with a parent
   and age<>youngage /*and the youngage age listed is not their own
   and rnd(youngage)<>youngage kidhashealth= 1. /*and the age isn't integer, assign 1.
compute age= rnd(age). /*Restore integer age
exec.
delete vari parent youngage1 youngage2 youngage.
