Predictions for Cox model

Description:

     Compute fitted values and regression terms for a model fitted by
     'coxph'

Usage:

     ## S3 method for class 'coxph':
     predict(object, newdata, type=c("lp", "risk", "expected", "terms"), se.fit=FALSE, terms=names(object$assign), collapse, safe=FALSE,...)

Arguments:

  object: A 'coxph' object

 newdata: Optional new data to predict at

    type: Type of prediction wanted

  se.fit: Return standard errors as well?

   terms: If 'type="terms"', which terms to return.

collapse: identifier for which rows correspond to different individuals

    safe: Use a more intensive `safe' prediction method

     ...: other unused arguments

Value:

     A vector or matrix of fitted values. If 'se.fit=TRUE' a list whose
     first component is the fitted values and second is the standard
     errors.

     fit<-coxph(Surv(time,status)~x,data=aml)
     predict(fit,type="lp")
     predict(fit,type="risk")
     predict(fit,type="expected")
     predict(fit,type="terms")
     predict(fit,type="lp",se.fit=TRUE)
     predict(fit,type="risk",se.fit=TRUE)
     predict(fit,type="expected",se.fit=TRUE)
     predict(fit,type="terms",se.fit=TRUE)
