6# caixiaoqiong 您好,我想您的问题已经得到解决,恭喜你。但是,我去掉这个复选框后,运行的时候出现了问题提示:An error occured while attempting to fit the model. In order to analyse date with missing observations,you must explicity estimate means and intercepts. In Amos Graphics,place a check mark next to "estimate means and intercepts"in th "Analysis Properties"window. In programming the Amos engine,use the modelmeanandinterceps method. 怎么办??
