Hi,

I ran the LPA model and got the errors below. I tried STARTS = 500 50 but the model does not converge.

title:
2-Class Latent Profile Analysis
of Peer Nominations Wave 2 REAL Data;
data: file is "G:\JADP.dat";
variable:
names=x1-x10;
classes=c(2);
analysis:
type=mixture;
STARTS = 500 50;

PLOT:
TYPE=PLOT3;
SERIES IS x1(1) x2(2) x3(3) x4(4) x5(5) x6(6) x7(7) X8(8) x9(9) x10 (10);
model:

OUTPUT:
TECH1 TECH5 TECH10;

SAVEDATA:
FILE IS myfile2c.dat;
SAVE = CPROBABILITIES;




RANDOM STARTS RESULTS RANKED FROM THE BEST TO THE WORST LOGLIKELIHOOD VALUES

199 perturbed starting value run(s) did not converge in the initial stage
optimizations.

Final stage loglikelihood values at local maxima, seeds, and initial stage start numbers:


50 perturbed starting value run(s) did not converge.


THE LOGLIKELIHOOD DECREASED IN THE LAST EM ITERATION. 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.

We would have to see the data and output to diagnose this. Send to Support.
