初学sem,处理问卷数据,问卷数据来源不太可靠,于是运行lisrel时出现以下几个提示: 1.W_A_R_N_I_N_G: PHI is not positive definite 2.W_A_R_N_I_N_G: THETA-DELTA is not positive definite 3. 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 而且加了pd命令,路径图仍出不来,求教各位 大虾指点,这三个报警提示是什么意思,谢谢! |
