Comp2ROC (version 1.0)

comp.roc.delong: 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)

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

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

Details

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

Examples

#data(zhang)
#moda1="mod1" 
#moda2="mod2"
#data=read.manually.introduced(zhang, moda1,TRUE, moda2, 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)
