| Qsearch.Fractil {newTestSurvRec} | R Documentation |
Calculate the survival time to a selected quantile
Description
Auxiliary function called from Dif.Surv.Rec function. Given a FitSurvRec object we obtain the quantile from a survival function using PHS o WC estimators.
Usage
Qsearch.Fractil(fr, qr = 0.5)Arguments
fr |
FitSurvRec object |
qr |
quantile. Default is 0.5 |
Value
Returns the time in a selected quantile
