model_performance.RHelper functions for model_performance.R
surv_model_performance(
explainer,
...,
times = NULL,
type = "metrics",
metrics = NULL
)Either a list when type == "metrics" or a data.frame if type == "roc"
an explainer object - model preprocessed by the explain() function
other parameters, currently ignored
a numeric vector, time points at which ROC curves are calculated if type == "roc" or at which metrics are calculated if type == "metrics". Note: if type=="roc" this parameter is obligatory
character, either "metrics" which calculates performance metrics or "roc" which calculates ROC curves at specific time points
a named vector containing the metrics to be calculated. The values should be standardized loss functions. The functions can be supplied manually but has to have these named parameters (y_true, risk, surv, times), where y_true represents the survival::Surv object with observed times and statuses, risk is the risk score calculated by the model, and surv is the survival function for each observation evaluated at times.
