I have some convergence problem. I think I should use some starting values. I know, how to do this technically with Mplus, but I do not know which specific value I should define for parameter 29 (see above). Can you give me some advices how I get the right value? Is there a general rule?
I get following message: THE STANDARD ERRORS OF THE MODEL PARAMETER ESTIMATES MAY NOT BE TRUSTWORTHY FOR SOME PARAMETERS DUE TO A NON-POSITIVE DEFINITE FIRST-ORDER DERIVATIVE PRODUCT MATRIX. THIS MAY BE DUE TO THE STARTING VALUES BUT MAY ALSO BE AN INDICATION OF MODEL NONIDENTIFICATION. THE CONDITION NUMBER IS 0.306D-17. PROBLEM INVOLVING PARAMETER 29.
