In iMRMC: Multi-Reader, Multi-Case Analysis Methods (ROC, Agreement, and Other Metrics)

Empirically average over multiple empirical ROC curves

Description

Empirically average over multiple empirical ROC curves

Usage

doROCavg(ROC, direction = "SeSp")

Arguments

ROC

list of ROC curves. Each element of the list is a data frame with pairs of (fpf, tpf) operating points.

direction

the direction over which to average SeSp (default) The ROC curves are averaged diagonally. Average Se+Sp of all the input ROC curves for every possible Se-Sp. Se The ROC curves are averaged vertically. Average the sensitivity of all the input ROC curves for every possible specificity. Sp The ROC curves are averaged horizontally. Average the specificity of all the input ROC curves for every possible specificity.

Value

data frame of an ROC curve

• fpf False-positive fractions (1-specificity)

• tpf True-positive fractions (sensitivity)
