CHAPTER 12saved in an external file for further investigation. Chapter 19 discussesthe options of the MONTECARLO command.Monte Carlo data generation can include the following special features:• Single or multiple group analysis for non-mixture models• Missing data• Complex survey data• Latent variable interactions and non-linear factor analysis usingmaximum likelihood• Random slopes• Individually-varying times of observations• Linear and non-linear parameter constraints• Indirect effects including specific paths• Maximum likelihood estimation for all outcome types• Wald chi-square test of parameter equalities• Analysis with between-level categorical latent variablesMultiple group data generation is specified by using the NGROUPSoption of the MONTECARLO command and the MODELPOPULATION-label command. Missing data generation is specified byusing the PATMISS and PATPROBS options of the MONTECARLOcommand or the MISSING option of the MONTECARLO command inconjunction with the MODEL MISSING command. Complex surveydata are generated by using the TYPE=TWOLEVEL option of theANALYSIS command in conjunction with the NCSIZES and CSIZESoptions of the MONTECARLO command. Latent variable interactionsare generated by using the | symbol of the MODEL POPULATIONcommand in conjunction with the XWITH option of the MODELPOPULATION command. Random slopes are generated by using the |symbol of the MODEL POPULATION command in conjunction withthe ON option of the MODEL POPULATION command. Individuallyvaryingtimes of observations are generated by using the | symbol of theMODEL POPULATION command in conjunction with the AT option ofthe MODEL POPULATION command and the TSCORES option of theMONTECARLO command. Linear and non-linear parameter constraintsare specified by using the MODEL CONSTRAINT command. Indirecteffects are specified by using the MODEL INDIRECT command.Maximum likelihood estimation is specified by using the ESTIMATORoption of the ANALYSIS command. The MODEL TEST command isused to test linear restrictions on the parameters in the MODEL and358
