CHAPTER 16For the FAY resampling method, a constant can be given that is used tomodify the sample weights. The constant must range between zero andone. The default is .3. The REPSE option for the FAY setting isspecified as follows:REPSE = FAY (.5);where .5 is the constant used to modify the sample weights.BASEHAZARDThe BASEHAZARD option is used in continuous-time survival analysisto specify whether a non-parametric or a parametric baseline hazardfunction is used in the estimation of the model. The default is OFFwhich uses the non-parametric baseline hazard function. Following is anexample of how to request a parametric baseline hazard function:BASEHAZARD = ON;With TYPE=MIXTURE, the OFF setting has two settings, EQUAL andUNEQUAL. The EQUAL setting is the default. With the EQUALsetting, the baseline hazard parameters are held equal across classes. Torelax this equality, specify:BASEHAZARD = OFF (UNEQUAL);CHOLESKYThe CHOLESKY option is used in conjunction withALGORITHM=INTEGRATION to decompose the continuous latentvariable covariance matrix and the observed variable residual covariancematrix into orthogonal components in order to improve the optimization.The optimization algorithm starts out with Fisher Scoring used incombination with EM. The CHOLESKY option has two settings: ONand OFF. The default when all dependent variables are censored,categorical, and counts is ON except for categorical dependent variableswhen LINK=PROBIT. Then and in all other cases, it is OFF. To turnthe CHOLESKY option ON, specify:CHOLESKY = ON;542
