Dear Lazar
I hope you are well, I am trying to do Multi group comparisons using Lisrel but I keep receiving the following error, Can you kindly assist.
W_A_R_N_I_N_G: Matrix to be analyzed is not positive definite,
ridge option taken with ridge constant = 10.000
I just wanted to ask a question pertaining to probability. Is that so hard?
