comp.roc.delong {Comp2ROC}

Calculate areas and stats

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)
