Test AUC pair results.

Source: R/AUCTest.R

Estimate significance of difference in two AUCs by resampling.

testAUCpair(
  d,
  model1Name,
  model2Name,
  yName,
  yTarget = TRUE,
  ...,
  na.rm = FALSE,
  returnScores = FALSE,
  nrep = 100,
  parallelCluster = NULL
)

Arguments

d

data.frame
model1Name

character model 1 column name

character model 2 column name
yName

character outcome column name
yTarget

target to match to y
...

extra arguments (not used)
na.rm

logical, if TRUE remove NA values
returnScores

logical if TRUE return detailed resampledScores
nrep

number of re-sample repetition to estimate p value.
parallelCluster

(optional) a cluster object created by package parallel or package snow

Value
