In RJafroc: Artificial Intelligence Systems and Observer Performance

Simulates a binormal model ROC dataset

Description

Simulates an uncorrelated binormal model ROC factorial dataset

Usage

SimulateRocDataset(I = 1, J = 1, K1, K2, a, b, seed = NULL)

Arguments

I	The number of modalities, default is 1
J	The number of readers, default is 1
K1	The number of non-diseased cases
K2	The number of diseased cases
a	The a parameter of the binormal model
b	The b parameter of the binormal model
seed	The initial seed, default is NULL, which results in a random seed

Details

See book Chapter 6 for details

Value

An ROC dataset
