Description

Computes confidence interval for the difference in the area under the curve based on two paired samples.

Usage

confIntPairedAUCDiff(cases, controls, conf.level = 0.95)

Arguments

cases	Matrix with values of the continuous variable for the cases. First column gives values of test A, second gives values of test B.
controls	Matrix with values of the continuous variable for the controls. First column gives values of test A, second gives values of test B.
conf.level	Confidence level for confidence interval.
