Return the Survival Continuously Ranked Probability Score (SCRPS) of a ReSurv model.

# Default S3 method
survival_crps(ReSurvFit, user_data_set = NULL)

Arguments

ReSurvFit

ReSurvFit object to use for the score computation.

user_data_set

data.frame provided from the user to compute the survival CRPS, optional.

Value

Survival CRPS, data.table that contains the CRPS (crps) for each observation (id).

Details

The model fit uses the theoretical framework of Hiabu et al. (2023), that relies on the
