          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
