When theMONTECARLO command is used, however, the NAMES andNOBSERVATIONS options are required. Default settings are shown inthe last column. If the default settings are appropriate for the analysis,nothing besides the required options needs to be specified. Following isa description of the MONTECARLO command.GENERAL SPECIFICATIONSThe NAMES, NOBSERVATIONS, NGROUPS, NREPS, and SEEDoptions are used to give the basic specifications for a Monte Carlosimulation study. These options are described below.NAMESThe NAMES option is used to assign names to the variables in thegenerated data sets. These names are used in the MODELPOPULATION and MODEL commands to specify the data generationand analysis models. As in regular analysis, the list feature can be used690
