TITLE: cat1
EFA for dichotomous items
DATA:
FILE IS wefa.dat;
VARIABLE:
NAMES ARE y1-y25;
USEV = y10-y22;
CATEGORICAL = y10-y22;
! all analysis variables are analyzed as categorical.
! Mplus determines that all are dichotomous.
ANALYSIS:
TYPE = EFA 1 2;
! a 1- and 2-factor solution is requested
ESTIMATOR = WLSMV;
! the default ULS estimator is replaced by an estimator
! that gives a chi-square test of model fit
