在lisrel中遇到几个问题,求解决:
问题是:W_A_R_N_I_N_G: PSI is not positive definite
W_A_R_N_I_N_G: The solution was found non-admissible after 255 iterations.
The following solution is preliminary and is provided only
for the purpose of tracing the source of the problem.
Setting AD>255 or AD=OFF may solve the problem
