- Section Headers —
TITLE:, DATA:, VARIABLE:, MODEL:, ANALYSIS:, OUTPUT:, PLOT:, SAVEDATA:, MONTECARLO:
- Model Operators —
BY, ON, WITH, PWITH, XWITH, IND, VIA, MOD, AT, NEW
- Estimators —
ML, MLR, MLM, WLSMV, BAYES, ULS, and more
- Analysis Types —
TWOLEVEL, MIXTURE, EFA, ESEM, RANDOM, COMPLEX
- Functions — Mathematical (
ABS, EXP, LOG, SQRT), Statistical (MEAN, VARIANCE, SUM), Distributions (NORMAL, POISSON, BINOMIAL)
- Rotation Methods —
GEOMIN, PROMAX, VARIMAX, OBLIMIN, TARGET, BIFACTOR
- Comments — Lines starting with
!
- Strings & Numbers — Quoted text and numeric values
- Variable Ranges —
y1-y6 style notation
- Constraint Labels — Parameter labels like
(a1), (loading)
