求助:Amos无法分析

<br /> 初用Amos软件,诸多不熟练不熟悉。<img src="http://bbs.pinggu.org/images/smilies/boshi/07.gif" smilieid="209" border="0" alt="" /> <br /> <br /> 中介效应分析:<br /> &nbsp; &nbsp; 按照吴明隆的书中所述,一步步画好模型图之后,导入数据分析运行模型。<br /> &nbsp; &nbsp; 然后,跳出出错提示框。<img src="http://bbs.pinggu.org/images/smilies/boshi/05.gif" smilieid="207" border="0" alt="" /> 无法运算结果。<br /> <br /> <br /> <br /> 提示框内容众多,具体如下:<br /> <br /> &nbsp;&nbsp;An error occurred while attempting to fit the model.<br /> &nbsp;&nbsp;The sample moment matrix is not positive definite. It could fail to be positive definite for any of the following reasons:<br /> &nbsp;&nbsp;1. The sample covariance matrix or the sample correlation matrix contains a data entry error.<br /> &nbsp;&nbsp;2. The observed variables are linearly dependent(perhaps because the sample size is too small).<br /> &nbsp;&nbsp;3. The sample covariance matrix or sample correlation matrix was computed from incomplete data using the method of “pairwise deletion”.<br /> &nbsp;&nbsp;4. The sample correlation matrix contains correlation coefficients other than product moment correlations(such as tetrachoric correlations).<br /> For maximum likelihood estimation only,it may be appropriate to check“allow non-positive definite sample covariance matrices”in the “Analysis Properties”window,or to use the Nonpositive method.<br /> <br /> 数据样本 来自spss数据<br /> 样本大小:1500<br /> 用spss已作出不完全中介效应。<br /> <br /> <br /> 这个提示说的主要问题,是数据不是正态分布么?(心里别说我小白啊小白啊小白啊……)<br /> 有什么方法可以解决呢? 还是说……不能用Amos?<img src="http://bbs.pinggu.org/images/smilies/default/em19.gif" smilieid="153" border="0" alt="" /> <br /> <br /> 真心诚意虽不是十万火急但还是挺着急地向各位请教~~~
