roc.curves.boot: Compare curves

In Comp2ROC: Compare Two ROC Curves that Intersect

Description

This is the function which control the whole package.This uses all functions except the reading ones and rocboot.summary and save.file.summary.

Usage

roc.curves.boot(data, nb = 1000, alfa = 0.05, name, mod1, mod2, paired)

Arguments

data	Data obtained throught read.file or read.manually.introduced
nb	Number of permutations
alfa	Confidance level for parametric methods
name	Name too show in graphs
mod1	Name of Modality 1
mod2	Name of Modality 2
paired	Boolean parameter that represents if the two modalities are related or not

Value

This function returns a list with:

Area1	Area of Curve 1
SE1	Standard error of Curve 1
Area2	Area of Curve 2
SE2	Standard error of Curve 2
CorrCoef	Correlation Coeficient
diff	Difference Between Areas (TS)
zstats	Z Statistic
pvalue1	p-value of Z Statistics
TrapArea1	Area of curve 1 using the Trapezoidal rule
TrapArea2	Area of curve 2 using the Trapezoidal rule
bootpvalue	p-value of bootstrapping
nCross	Number of Crossings
ICLB1	Confidance Interval: Lower Bound for Curve 1
ICUB1	Confidance Interval: Upper Bound for Curve 1
ICLB2	Confidance Interval: Lower Bound for Curve 2
ICUB2	Confidance Interval: Upper Bound for Curve 2
ICLBDiff	Confidance Interval: Lower Bound for Difference between areas
ICUBDiff	Confidance Interval: Upper Bound for Difference between areas

Examples

data(zhang)
nameE = "new_Zhang"
modality1DataColumn = "modality1"
modality2DataColumn = "modality2"
data = read.manually.introduced(zhang, moda1, TRUE, moda2, TRUE, "status", TRUE)
results = roc.curves.boot(zhang, 1000, 0.05, name=nameE,
                          mod1=modality1DataColumn, mod2=modality2DataColumn)
