仿照老外的Mplus多层结构方程模型程序,运行后结果输出显示“CHANGE YOUR MODEL AND/OR STARTING VALUES.”,请教高人知道怎样设置这个starting value,谢谢! 原来用过EQS6.1,当出现迭代不能收敛时,也需要设定初始值,在EQS中有专门的语句可以用蒙特卡罗方法把初始值估计出来,使用者只要原样复制就OK了,我检查了哪些初始值,有正数,负数,小数,我想人工去尝试设置的话,只怕是不可能的事,就想问下有哪位高人可以指点(哪怕是指点相关的参考资料也可以)再次感谢! 作者: sopheia 时间: 2011-7-2 17:46
有知道的吗?作者: 统计分析 时间: 2011-7-2 17:51
看看对你是否有用: If a parameter is not free by default, when the parameter is mentioned in the MODEL command, it is free at the default starting value unless another starting value is specified using the asterisk (*) followed by a number or the parameter is fixed using the @ symbol followed by a number. The exception to this is that variances and residual variances for latent response variables corresponding to categorical observed dependent variables cannot be free in the Delta parameterization. They can be free in the Theta parameterization. In the Theta parameterization, scale factors for latent response variables corresponding to categorical observed dependent variables cannot be free. They can be free in the Delta parameterization. GENERAL DEFAULTS Following are the default starting values: Means/intercepts of continuous and 0 or sample mean censored observed variables depending on the analysis Means/intercepts of count observed variables 0 Thresholds of categorical observed variables 0 or determined by the sample proportions depending on the analysis Variances/residual variances of .05 or 1 depending on continuous latent variables the analysis Variances/residual variances of .5 of the sample continuous and censored observed variables variance Variances/residual variances of 1 latent response variables for categorical observed variables Scale factors 1 Loadings for indicators of continuous 1 latent variables All other parameters 0 For situations where starting values depend on the analysis, the starting values can be found using the TECH1 option of the OUTPUT command.作者: 51jijin 时间: 2011-7-2 17:56
非常感谢你的帮助,最后一句试试看有没有用。作者: 因子分析 时间: 2011-7-2 18:01
