<div><span>昨天用amos 跑了数据，得出的卡方值超大<span>（Chi-square = <span x="3236.27113081325" h="-1">3236.271，</span></span>Degrees of freedom = 1019，<span h="-1">Probability level = <span x="1.37363947634162E-228" h="-1">.000）</span></span>，说明模型拟合很不好。再仔细一看，自由度怎么也那么大，我看别人做的自由度都只在100之内。</span></div><div><span></span></div><div><span>有三个问题向各位大牛们请教：</span></div><div><span>1.&nbsp; 自由度这么大，说明模型设定上有什么问题或要做什么修改吗？</span></div><div><span></span></div><div><span>2.&nbsp; 通常说卡方值越小越好，那么社会科学研究中一般可接受最大到多少？比如100以内，或是1000以内？</span></div><div><span></span></div><div><span>3.&nbsp; 还有一个菜鸟级小问题，我想在模型上多加一些相关关系，拖曳了双箭头图标，为什么在模型图上没有任何反应？</span></div><div><span></span></div><div><span></span></div><div><span>望有经验的各位不吝赐教，受益的一定不止我一个。谢谢啦。</span></div><div><span></span></div><div><span h="-1"><span x="1.37363947634162E-228" h="-1"></span></span></div><div nodecaption="Group number 1" caption="Group number 1" ntype="group" style="DISPLAY: none;"><div style="DISPLAY: none;"></div><div nodecaption="Modification Indices" caption="Modification Indices"><div nodecaption="Variances:"><div nodecaption="Minimization History" ntype="minimizationhistory" style="DISPLAY: none;"></div></div></div></div><div nodecaption="Minimization History" ntype="minimizationhistory" style="DISPLAY: none;"></div>
