Wang, Chao [Software producer] (2018) MC: Stata module to calculate a matched concordance index. RePEc IDEAS.

Abstract

The concordance index, equivalent to the area under the receiver operating characteristic (ROC) curve (AUC) for binary outcomes, is often used to measure the discriminatory power of a variable. However, the C-index may be inappropriate for matched case-control or panel data since it ignores matching. This program calculates the matched C-index (i.e. a C-index conditional on matching) proposed by Brentnall et al. (2015) as an alternative measure for matched case-control or panel data. It supports matched groups of variable sizes and bootstrapped confidence intervals.
