spss - 为空单元格生成平均值

Question

我是 SPSS 新手，我正在尝试为空单元格生成平均值（基本上通过用户给出的平均答案填写缺失的信息），我无法让我的示例代码工作（或很好地理解示例）。

COMPUTE QOL_puutt = Nmiss(ass, bass, grass, gas).

这部分我明白

Do repeat A  = ass1 ass2  ass3. If ((Missing (A)) & QOL_puutt <= 4) A
= RND(Mean (ass1, ass2, ass3)).  End repeat.

这里出了点问题。我知道 ass1,ass2,ass3 是指单元格（第 3 列）？？？以下是错误代码

Error # 4285 in column 15. Text: ass1 Incorrect variable name: either the name is more than 64 characters, or it is not defined by a previous command. Execution of this command stops.

Error # 4285 in column 15. Text: ass2 Incorrect variable name: either the name is more than 64 characters, or it is not defined by a previous command. Execution of this command stops.

Error # 4285 in column 15. Text: ass3 Incorrect variable name: either the name is more than 64 characters, or it is not defined by a previous command. Execution of this command stops

Answer 1

由于包装，很难说出代码是什么，但您可以像这样简化它 do repeatA = ass1 ass2 ass3. 如果缺少（A）A = 平均值（屁股，低音，草，气）。结束重复。

如果缺少所有值，mean 将自动返回 sysmis。如果您想要求一定数量的非缺失值，例如 2，您可以将语句编写为缺少（A）A = mean.2(ass, bass, Grass, gas)。
