帮忙看看这是啥错误
<br /> 刚学sem在用amos<br /> <br /> 总是提示我这个问题，怎么改都不行，高手老手帮看看<br /> An error occurred while attempting to fit the model.<br /> In order to analyse data with missing observations,you must explicity estimate means and intercepts.<br /> In Amos Graphics,place acheck mark next to "Estimate means and intercepts"in the "Analysis Properties" window.<br /> In programming the Amos engine,use the ModelMeansAndIntercepts method.<br /> 还有这个The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 1 additional constraint.<br /> <br /> 非常感谢 1、第一个是你数据文件有缺省值，当有缺省值时，只能把estimate means and intercepts选项勾上，菜能运行<br /> 2、第二个情况很多，如果运行没有提示其他错误，那就是你的数据和你的模型还没有较好的拟合；或者自由度不够，先计算下自由度 <strong> 2# <i>ywh19860616</i> </strong><br /> <br /> <br /> 谢谢楼上的 我勾上了那个了<br /> 我自由度四百多 有点诡异。。。。页:
