Dr. Muthen,

I tried to run a SEM model on 4 latent variables, 21 binary indicators and 1 continuous indicator. I got ¡§NO CONVERGENCE. NUMBER OF ITERATIONS EXCEEDED¡¨. I am not sure what goes wrong with the model? Appreciate if you could advise.

TITLE: dis data

DATA: File IS "C:\My Documents\Files\vbn.csv";

Format IS free;

VARIABLE:
NAMES ARE sex ds age y1 y2 y3 y4 y5 y6 y7 y8 y9 y10 y11 y12 y13
y14 y15 y16 y17 y18 y19;
USEVARIABLES= sex ds age y1 y2 y3 y4 y5
y6 y7 y9 y10 y11 y13 y14 y15 y16 y17 y18 y19;
CATEGORICAL ARE sex ds y1 y2 y3 y4 y5
y6 y7 y9 y10 y11 y13 y14 y15 y16 y17 y18 y19;
Missing=ALL (999);

ANALYSIS:
Type=General;
Estimator=WLSMV;
CONVERGENCE = 0.000001;
Parameterization=DELTA;
ITERATIONS=10000;

MODEL:
f1 BY y1@1 y2 y3 y18 y19;
y2 WITH y3;
f2 BY y4@1 y5 y6 y7 y9 y10 y17 ;
y4 WITH SEX;
f3 BY y15@1 y16 y14 y13;
y14 WITH y15;
f4 BY SEX@1 AGE;
SEX WITH AGE@0;
SEX WITH DS@0;
f4 on f1 f2 f3;
f4@0;

Many thanks!
