I am receiving this error for a model with good fit and sound findings that support our theory:
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 -0.219D-17. PROBLEM INVOLVING THE FOLLOWING PARAMETER: Parameter 67, W2HEDO
I don't see any problems in the TECH4 output -- where else could I look to see what the problem is?
