NAG's IFAIL parameter is 1 We probably have a minimum here, but you might consider trying different starting values. You can randomize these with TH=n on the OU line, where n is the number of times you wish to do this. I STRONGLY recommend BOundaries to be set if you use TH MX PARAMETER ESTIMATES GROUP NUMBER: 1 MULTITRAIT-MULTIMETHOD ANALYSIS MATRIX E This is a DIAGONAL matrix of order 12 by 12 1 2 3 4 5 1 6.9814E-01 2 0.0000E+00 5.7106E-01 3 0.0000E+00 0.0000E+00 3.0774E-06 4 0.0000E+00 0.0000E+00 0.0000E+00 1.7502E-01 5 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 1.6166E-01 6 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 7 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 8 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 9 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 10 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 11 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 12 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 6 7 8 9 10 1 2 3 4 5 6 1.2833E-01 7 0.0000E+00 5.0391E-01 8 0.0000E+00 0.0000E+00 6.7234E-01 9 0.0000E+00 0.0000E+00 0.0000E+00 5.2014E-01 10 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 3.7527E-01 11 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 12 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 11 12 1 2 3 4 5 6 7 8 9 10 11 5.3890E-01 12 0.0000E+00 4.9023E-01 MATRIX I This is an IDENTITY matrix of order 4 by 4 MATRIX J This is an IDENTITY matrix of order 3 by 3 MATRIX L This is a STANDARDISED matrix of order 4 by 4 1 2 3 4 1 1.0000 2 0.1738 1.0000 3 -0.2294 0.1649 1.0000 4 0.2289 0.5069 0.3316 1.0000 MATRIX M This is a FULL matrix of order 3 by 4 1 2 3 4 1 0.1656 0.4756 0.5618 0.8018 2 0.4689 0.7332 0.5493 0.7595 3 0.7451 0.8056 0.3829 0.6769 MATRIX S This is a STANDARDISED matrix of order 3 by 3 1 2 3 1 1.0000 2 0.6086 1.0000 3 0.0398 0.2397 1.0000 MATRIX T This is a FULL matrix of order 4 by 3 1 2 3 1 0.7022 0.6510 0.7050 2 0.9144 0.6926 0.6063 3 0.6491 0.5778 0.7393 4 0.5278 0.4260 0.5284 MATRIX U This is a UNIT matrix of order 4 by 1 MATRIX V This is a UNIT matrix of order 3 by 1 *WARNING* Minimization may not be successful.
