In sMSROC: Assessment of Diagnostic and Prognostic Markers

Confidence intervals for the AUC (empirical variance estimation)

Description

Computation of confidence intervals for the AUC by implementing the empirical procedure for estimating the variance of the AUC, as described in \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1515/ijb-2019-0097")}.

Usage

auc_ci_empr(SE, SP, auc, probs, controls, cases, ci.cl)

Arguments

SE	vector containing the values of the sensitivity returned from the sMSROC function.
SP	vector containing the values of the specificity.
auc	value with the AUC estimate.
probs	vector containing the probabilities estimated through the predictive model.
controls	number of negative individuals.
cases	number of positive individuals.
ci.cl	confidence level at which confidence intervals will be computed.

Value

List with two components:

ic.l	lower edge of the confidence interval.
ic.u	upper edge of the confidence interval.
