Other unused arguments

Value

• call
  The shared frailty model evaluated.
• frequencies
  Numbers of patients, events and groups used to fit the model.
• Nboot
  Number of bootstrap resamplings required.
• Nbproblem
  Number of bootstrap resamplings in which the model did not converge. Those are excluded when computing the standard-error and the percentile 95% confidence interval.
• ties
  A binary, indicating if the pairs tied on prediction were used to compute the concordance.
• CPEcond
  Values of the Concordance Probability Estimations (conditional) and the number of pairs used. If Nboot>0, give SE, the standard-error of the parameters evaluated by bootstrap, IC.low and IC.high, the lower and upper bounds of the percentile confidence interval evaluated by bootstrap (2.5% and 97.5% percentiles).
• marginal
  A binary, indicating if the marginal values were computed.
• CPEmarg
  Values of the Concordance Probability Estimations (marginal) and the number of pairs used, if marginal=1. If Nboot>0, give SE, the standard-error of the parameters evaluated by bootstrap, IC.low and IC.high, the lower and upper bounds of the percentile confidence interval evaluated by bootstrap (2.5% and 97.5% percentiles).
• cindex
  A binary, indicating if the c-indexes were computed.
• cindexcond
  Values of the C-index (conditional) and the number of pairs used. If Nboot>0, give SE, the standard-error of the parameters evaluated by bootstrap, IC.low and IC.high, the lower and upper bounds of the percentile confidence interval evaluated by bootstrap (2.5% and 97.5% percentiles).
• cindexmarg
  Values of the C-index (marginal) and the number of pairs used, if marginal=1. If Nboot>0, give SE, the standard-error of the parameters evaluated by bootstrap, IC.low and IC.high, the lower and upper bounds of the percentile confidence interval evaluated by bootstrap (2.5% and 97.5% percentiles).

Examples

## load data
data(readmission)

## a frailtypenal fit
fit.frailtypenal <-frailtyPenal(Surv(time,event)~as.factor(dukes)+cluster(id)+
as.factor(charlson)+strata(sex)+as.factor(chemo),data=readmission,Frailty=TRUE,
cross.validation=FALSE,n.knots=10,kappa1=1,kappa2=1,hazard="Splines")

## a Cmeasures call
fit.Cmeasures <- Cmeasures(fit.frailtypenal)

## a short summary
print(fit.Cmeasures)
