MONTECARLO Commandvariable the number sign (#) followed by the number 1. The baselinehazard parameters in continuous-time survival analysis are referred to byadding to the name of the time-to-event variable the number sign (#)followed by a number. There are as many baseline hazard parameters asthere are time intervals plus one.CUTPOINTSThe CUTPOINTS option is used to create binary independent variablesfrom the multivariate normal independent variables generated by theprogram. The CUTPOINTS option specifies the value of the cutpoint tobe used in categorizing an independent variable. Following is anexample of how the CUTPOINTS option is specified:CUTPOINTS = x1 (0) x2 ( 1);where x1 has a cutpoint of 0 and x2 has a cutpoint of 1. For x1,observations having a value less than or equal to 0 are assigned the valueof zero and observations having values greater than 0 are assigned thevalue of one. Any independent variable not mentioned using theCUTPOINTS option is assumed to be continuous.In multiple group analysis, the CUTPOINT option is specified as followswhere the cutpoints for the groups are separated using the | symbol:CUTPOINTS = x1 (0) x2 ( 1) | x1 (1) x2 (0);where the cutpoints before the | symbol are the cutpoints for group 1 andthe cutpoints after the | symbol are the cutpoints for group 2.GENCLASSESThe GENCLASSES option is used to assign names to the categoricallatent variables in the data generation model and to specify the numberof latent classes to be used for data generation. This option is used inconjunction with TYPE=MIXTURE. The GENCLASSES option isspecified as follows:GENCLASSES = c1 (3) c2 (2) c3 (3);695
