我的结果出来后卡方值特别大，想修正一下，但按照书上的做法，选了修正指标这一项，没想到出现这样的结果，有没有好心人帮忙看一看。
An error occurred while attempting to fit the model.
Modification indices cannot be computed incomplete data.
if you are using Amos Graphics,remove the check mark next to "Modification indices" in the "Analysis Properties" window.
if you are programming the Amos engine,do not use the Mods method.
这是怎么回事呀？
