我现在在做一个二阶因子分析模型,输出中出现warning,说PSI ,THETA-EPS非正定,还说经过50次迭代后参数估计的解不可接受(原文:W_A_R_N_I_N_G: The solution was found non-admissible after 50 iterations.
The following solution is preliminary and is provided only
for the purpose of tracing the source of the problem.
Setting AD> 50 or AD=OFF may solve the problem)
但是我在做一阶因子模型(验证性因子分析)时效果还可以,卡方自由度比<5,RMSEA= 0.094,CFI = 0.90。那么到底是哪里出现问题了呢?该如何解决呢?
我是初学者,希望大家帮忙指导一下~~谢谢大家了~~
