loss_integrate {survex} | R Documentation |
Calculate integrated metrics based on time-dependent metrics.
Description
This function allows for creating a function for calculation of integrated metrics based on a time dependent metric. A possibility to cut off the data at certain quantiles is implemented, as well as weighting the integrated metric by max time and marginal survival function [1]
Usage
loss_integrate(loss_function, ..., normalization = NULL, max_quantile = 1)

Value
a function that can be used to calculate metrics (with parameters y_true
, risk
, surv
, and times
)
