另外 在researchgate上得到的一个回答也很有建设性意义,最后我是根据他的回答用stata做了multivariate regression。后测用WALD test. 因为比较简单方便。
大家遇到类似的问题,也可以用SEM做。
下面附上回答:
Dear Fan,
First of all, what is the statistical question you would like to answer?
There is nothing in data that forces us to think a certain way. It is the other way around.
Now, if the interest in your 4 DVs are separate - as is, you plan to look at all of the relationships between IV and each DV on its own because these represent meaningful and important answers to you - then you can use 4 univariate tests for this.
If your interest is in whether their is a joint effect (across all 4 DVs but you are indifferent to which) or you wish to compare the coefficients across DVs then a multivariate test might be useful. SPSS can only handle multivariate regression within the MANOVA command which is why you were getting that advice. MANOVA does have a number of assumptions and requirements. GLLMMs can handle much of what MANOVA cannot.
What about SEM, PLS, and other alternatives? You have a very simple situation so unless you have a highly complicated hypothesis you probably don't need either one. That said, they can tell you about the pattern of relationships between IV and all 4 DVs just as the MANOVA
Consider going to a good site with examples (e.g. http://www.ats.ucla.edu/stat/dae/ )
to see if you can make up your mind a little bt about what you want to know.
Good luck.
