Assuming completely independent censoring, i.e., censoring does not depend on the survival time nor any covariates in the model, the pseudo observations are calculated with the standard jackknife approach
pseudo_independent( formula, time, cause = 1, data, type = c("cuminc", "survival", "rmean"), formula.censoring = NULL, ipcw.method = NULL )
A formula specifying the model. The left hand side must be a Surv object specifying a right censored survival or competing risks outcome. The status indicator, normally 0=alive, 1=dead. Other choices are TRUE/FALSE (TRUE = death) or 1/2 (2=death). For competing risks, the event variable will be a factor, whose first level is treated as censoring. The right hand side is the usual linear combination of covariates.
Numeric constant specifying the time at which the cumulative incidence or survival probability effect estimates are desired.
Numeric or character constant specifying the cause indicator of interest.
Data frame in which all variables of formula can be interpreted.
One of "survival", "cuminc", or "rmean"
Not used with this method
A vector of jackknife pseudo observations
