In BlanketStatsments: Build and Compare Statistical Models

Description

Calculate Uno's concordance statistic for any model. CAVE: If you want to evaluate a model trained on a different dataset, df should be limited to the test set.

Usage

calculate_Uno_c(df, model, verbose = FALSE)

Arguments

df	data.frame containing the data set. If evaluating independently, use the test set.
model	statistical model of type coxph to be evaluated.
verbose	logical. TRUE activates printout messages.

Value

double AUC value for the evaluated model on the specified data set.

Examples

data <- survival::lung
cancer_mod <- survival::coxph(survival::Surv(time, status)~age, data = data)
calculate_Uno_c(data, cancer_mod)
