Dear all,
I am trying to run a Two-level item bi-factor EFA in a dataset that combines different studies. I would like to know how to access the scripts mentioned in the article by Muthén and Asparouhov:
Item Response Modeling in Mplus:
A Multi-Dimensional, Multi-Level, and Multi-Timepoint Example.
It says in the abstract that the scripts are available here, but I couldn't find it.
I built the following syntax (but I'm not sure if it's correct):
VARIABLE:

MISSING ARE ALL (999);

NAMES ARE

BDI1
BDI2
BDI3
BDI4
BDI5
BDI6
BDI7
BDI8
BDI9
BDI10
BDI11
BDI12
BDI13
BDI14
BDI15
BDI16
BDI17
BDI18
BDI19
BDI20
BDI21
Level;

USEVARIABLES ARE

BDI1-BDI21
Level;

CLUSTER= Level;

ANALYSIS:
TYPE= TWOLEVEL EFA 2 3 UW 2 3 UB;
ROTATION= BI-GEOMIN;
ESTIMATOR= WLSMV;

However, when I ran it, I got this error message:
RESULTS FOR EXPLORATORY FACTOR ANALYSIS
CONVERGENCE PROBLEMS OCCURRED IN THE UNIVARIATE ESTIMATION OF
VARIABLE BDI11.
Any ideas why this happened? Does my syntax looks correct?
Bests,
Ricardo
