`time`	survival time
`delta`	event status (1 = event)
`X`	design matrix of survival part
`beta`	parameters of survival part
`Z`	design matrix of cure part
`b`	parameters of cure part
`model`	the type of survival model ("PH", "PO","Normal")
`baseline`	whether the surv is baseline survival probability
