Static survival metrics

Description

Static survival metrics evaluate survival predictions that do not depend on a specific evaluation time point. These metrics typically compare predicted risk scores or survival times against observed outcomes.

Input requirements

• truth: a survival::Surv() object

• estimate: numeric (predicted time or risk score)

Available metrics

concordance_survival()

Direction: maximize. Range: [0, 1]
