Amos 输出结果求救！

谢谢你！~~非常感谢！不过我还有一个问题，就是我在做CFA验证因素分析与聚合效度以及区别效度的结果模型的 ...

多质多法模型？这个主要是结果的差别，根据自己的理论来设定模型，SEM没什么差异，差异在结果不同。

请问各位大侠，Amos 的输出结果里面没有 RMR GFI 这一栏，导致我看不了 RMR GFI AGFI PGFI 这几个指标的相关值。会有什么原因导致吗？怎么解决这个问题！多谢各位了！！！

Amos does not report GFI, PGFI, AGFI and RMR when you estimate means and intercepts. This is because it is not clear how to incorporate means and intercepts into the conventional formulas for these statistics. One possibility is to calculate these statistics based on the observed variances/covariances and the fitted (implied) variances/covariances, leaving the means and intercepts out of the fit measure. That way of computing the statistics could be useful and is certainly defensible. It would make a great deal of sense in those models where means and intercepts are estimated but not constrained. On the other hand, for models that constrain means and intercepts it is important to pay attention to how well the model reproduces the means and intercepts, as well as the variances/covariances.

Another approach would be to generalize the definitions of those statistics to somehow incorporate failure to fit means and intercepts. So far, a unique, obviously correct, way of doing this has not been proposed.

For these reasons, the design decision was made not to report GFI, PGFI, AGFI and RMR when means and intercepts are estimated.
实际上，诸多模型是无法接近理想的拟合优度，如果需要根据MI值修正，你还需要看是否有理性支持你修正的理由。

高手高手！请问大侠对three-way interaction有没有什么研究? 就是两个moderator 同时影响两者之间的关系

老兄
因為你勾了ESTIMATE MEAN AND INTERCEPT
所以沒有GFI...等出現
把VIEW-->ANALYSIS PROPERTIES-->ESTIMATION-->ESTIMATE MEAN AND INTERCEPT的勾拿掉即可
記住,資料不可以有遺漏值,否則不能分析

谢谢谢谢！你说的我都一一尝试一遍！

聚合效度指的是每个构面的题项是否能代表该一构面
因此是在一开始执行cfa时就做的
而区别效度是指构面之间是否有差异
所以要在cfa完全有相关下进行
图是不一样的

我那个拿掉了就不能计算了，不能有遗漏是什么意思
