! INPUT FILE FOR EXAMPLE 7 from BG MS # 020404 by C Prescott
TITLE: Estimating Thresholds for input into THETA parameterization model
DATA: FILE = onset99.dat;
VARIABLE: NAMES = famno mpair zyg age dx1 abst1 onset1 dx2 abst2 onset2;
USEVARIABLEs = dx1 dx2 onset1 onset2;
CATEGORICAL = dx1 dx2 onset1 onset2 ;
USEOBS = zyg==3 or zyg==4;
GROUP = zyg(3=mzm 4=dzm);
MISSING = ALL(99);
DEFINE: CUT dx1(0); CUT dx2(0); ! for dsm4 abuse/dependence
DEFINE: CUT onset1(15); CUT onset2(15); ! recodes into binary variable
DEFINE: onset1=1-onset1; onset2=1-onset2; ! recoding to early=1 later=0
ANALYSIS: TYPE = MEANSTRUCTURE; PARAM=DELTA;
MODEL:
{dx1@1 dx2@1 onset1@1 onset2@1};
[dx1$1*.4] (1); [dx2$1*.4] (1);
[onset1$1*.8] (2); [onset2$1*.8] (2);
*** WARNING in Model command
All variables are assumed to be y-variables. Check that the covariances
between these and other variables are as intended.

TESTS OF MODEL FIT
Chi-Square Test of Model Fit
Value 656.075*
Degrees of Freedom 15**
P-Value 0.0000
* The chi-square value for MLM, MLR, MLMV, WLSM and WLSMV cannot be used for
chi-square difference tests. MLM and MLR chi-square difference testing is
described on page 360 in the Mplus User's Guide.
** The degrees of freedom for MLMV and WLSMV are estimated according to
formula 110 (page 358) in the Mplus User's Guide.
Chi-Square Test of Model Fit for the Baseline Model
Value 626.579
Degrees of Freedom 10
