comp.roc.delong: Calculate areas and stats

In Comp2ROC: Compare Two ROC Curves that Intersect

Description

This function allows to calculate the areas under the curve for each curve and some statistical measures.

Usage

comp.roc.delong(sim1.ind, sim1.sta, sim2.ind, sim2.sta, related = TRUE)

Arguments

sim1.ind	Vector with the data for Curve 1
sim1.sta	Vector with the status for Curve 1
sim2.ind	Vector with the data for Curve 2
sim2.sta	Vector with the status for Curve 2
related	Boolean parameter that represents if the two modalities are related or not

Details

This function calculates the Wilcoxon Mann Whitney matrix for each modality, areas, standard deviations, variances and global correlations.

Value

This function returns a list with:

Z	Hanley Z calculation
pvalue	p-value for this Z
AUC	Area under curve for each modality
SE	Standard error
S	Variance for each modality
R	Correlation Coeficient

Examples

data(zhang)
modality1DataColumn = "modality1"
modality2DataColumn = "modality2"
data = read.manually.introduced(zhang, modality1DataColumn, TRUE,
                                modality2DataColumn, TRUE, "status", TRUE)
sim1.ind = unlist(data[1])
sim2.ind = unlist(data[2])  
sim1.sta = unlist(data[3])
sim2.sta = unlist(data[4])
comp.roc.delong(sim1.ind, sim1.sta, sim2.ind, sim2.sta)
