用amos，把所有的前期工作全部做完，计算路径系数，可是怎么都算不出来。软件运行的结果为an error occurred while attempting to fit the model
in order to analyse data with observation ,you must explicitly estimate mean and intercepts . in amos graphics place a check mark next to “estimate means and intercepts”in the “properties”window
in programming the amos engine,use the model means and intercepts method
   那位大侠看看是存在于什么问题，和改进方法。万分感谢
