Dear,
Is it correct to say that this uses theta parameterization?
DATA:
FILE = three.dat;
VARIABLE:
NAMES = a1-a172;
CATEGORICAL = a2-a172;
USEVARIABLES = a1-a172;
MISSING = ALL(99);
IDVARIABLE = a1;
ANALYSIS:
ESTIMATOR = ML;
MODEL:
theta1 by a60-a111*
a52-a59* (a1-a8);
theta2 by a2-a9* (a1-a8)
a10-a17* (a9-a16)
a18-a51*;
theta3 by a112-a119* (a9-a16)
a120-a172*;
theta1-theta3@1;
[a52$1-a59$1] (b1-b8);
[a2$1-a9$1] (b1-b8);
[a10$1-a17$1] (b9-b16);
[a112$1-a119$1] (b9-b16);
PLOT:
TYPE = PLOT1 PLOT2 PLOT3;
SAVEDATA:
SAVE = FSCORES;
FILE = three.dat; |

| Edit: I used this syntax with 7.3 (some years ago). |

| Yes, ML with categorical indicators uses Theta parametrization. |
