Calculate AUC from sensitivity and specificity

Source: R/basic_metrics.R, R/diagnostic_metrics.R, R/utils.R
calculate_auc.Rd

Uses the formula shown in the package documentation example: 0.5 * (sens * (1 - spec)) + 0.5 * (1 * (1 - (1 - spec))) + 0.5 * ((1 - sens) * spec).

Uses a simplified formula to approximate AUC from sensitivity and specificity

Usage

calculate_auc(sens, spec)

calculate_auc(sens, spec)

calculate_auc(sens, spec)

Arguments

sens

Sensitivity of the test

spec

Specificity of the test

Value

Area under the ROC curve
