我用amos模型识别看出模型参数205个，其中自由的134个，样本资料所能提供的数据点为2211个，因此模型自由度是2077，所以可以识别
然后我允许模型拟合，一开始就没有反应了，后来给出如下提示，
an error occurred while attempting to fit the model
in order to analysis data with misssing observations, you must explicitly estimate means and intercepts
in Amos Graphics,place a check mark next to "extimate means and intercepts"in the "analysis properties" window
in programming the Amos engine, use the ModelMeansAndIntercepts method
第三行我看懂并执行了，但是最后一行怎么解决呀
