brierScore

Derives the Brier Scores (using Inverse Probability of Censoring Weighting) for the Survival estimates as detailed in blanche2015jmpost.

Usage

# S3 method for class 'SurvivalQuantities'
brierScore(object, maintain_cen_order = TRUE, event_offset = TRUE, ...)

Arguments

object

(SurvivalQuantities)
survival quantities.

maintain_cen_order

(logical)
If TRUE then, in the case of ties, censor times are always considered to have occurred after the event times when calculating the "reverse Kaplan-Meier" for the IPCW estimates. Setting this to TRUE mirrors the implementation of the {prodlim} package.

event_offset

(logical)
If TRUE then \(G(T_i)\) is evaluated at \(G(T_i-)\). Setting this as TRUE mirrors the implementation of the {pec} package.

...

not used.
