运行manova时出现SPSS错误

Question

我在使用SPSS时遇到了问题。当我尝试运行一个数据集时，它会说：

>Error # 12005 in column 14.  Text: -4
>A parenthesized value range in the MANOVA procedure contains a lower limit
>(the first value) that is greater than the upper limit (the second value).
>Execution of this command stops.

这是我试图运行的语法：

manova P_Progress, P_ObsComp, P_SocFdBk, P_PsyState
by Group4 (1,2,3,4) Group3 (1,2,3)/
print=cellinfo(means)
     homogeneity(all)
     error(cor)
     signif(multiv,univ,stepdown)/
omean=variables(P_Progress, P_ObsComp, P_SocFdBk, P_PsyState) tables(Group4, 
Group3)/plot=normal. 

我正在做一个双向的manova。

Answer 1

我建议参考有关MANOVA的IBM SPSS Statistics Syntax参考。MANOVA的语法应该是这样的：

MANOVA dependent varlist [BY factor list (min,max)[factor list...]
[WITH covariate list]]

我相信这段代码应该可以工作：

manova P_Progress, P_ObsComp, P_SocFdBk, P_PsyState
    by Group4 (1,4) Group3 (1,3)
  /print = cellinfo(means)
    homogeneity(all)
    error(cor)
    signif(multiv,univ,stepdown)
  /omean = variables(P_Progress, P_ObsComp, P_SocFdBk, P_PsyState)
    tables(Group4, Group3)
  /plot=normal.
