Good morning.
I am running a growth model on a particular subgroup in my sample but keep getting the following error message:
THE ESTIMATED COVARIANCE MATRIX COULD NOT BE INVERTED. COMPUTATION COULD NOT BE COMPLETED IN ITERATION 2. CHANGE YOUR MODEL AND/OR STARTING VALUES.
THE MODEL ESTIMATION DID NOT TERMINATE NORMALLY DUE TO AN ERROR IN THE COMPUTATION. CHANGE YOUR MODEL AND/OR STARTING VALUES.
My coding is as follows:
Variable:
NAMES ARE PTID TRAJCLASS
V1LOGTNF V2LOGTNF V3LOGTNF V4LOGTNF
V1sTNFR1 V2sTNFR1 V3sTNFR1 V4sTNFR1
USEVARIABLES ARE
V1LOGTNF V2LOGTNF V3LOGTNF V4LOGTNF;
MISSING ARE .;
!GROUPING IS TRAJCLASS(0=SUSTAINED 1=UNSUSTAINED);
USEOBSERVATIONS = TRAJCLASS eq 1;
ANALYSIS:
ESTIMATOR = ML;
ALGORITHM = INTEGRATION;
BOOTSTRAP = 1000;
MODEL: i1 s1 | V1LOGTNF@0 V2LOGTNF@1 V3LOGTNF@1 V4LOGTNF@1;
i1 s2 | V1LOGTNF@0 V2LOGTNF@0 V3LOGTNF@3 V4LOGTNF@6;
!i1 s1 s2 ON TRAJCLASS;
When I run the same code on the "SUSTAINED" group I do not receive and error message and get full output. Do you have any suggestions? Thanks so much. |

Try without bootstrap to see if that is the cause. If it is, see our FAQ
Bootstrap problems
Otherwise, we need to see your full output to be able to say - send to Support along with your license number. |
