Pseudovalues for given factorial or crossed modality dataset and FOM

Returns centered jackknife pseudovalues AND jackknife FOM values, for factorial study designs

UtilPseudoValues(dataset, FOM, FPFValue = 0.2)

Arguments

dataset

The dataset to be analyzed, see RJafroc-package.

FOM

The figure of merit to be used. The default is "FOM_wAFROC". See UtilFigureOfMerit.

FPFValue

Only needed for LROC data and FOM = "PCL" or "ALROC"; where to evaluate a partial curve based figure of merit. The default is 0.2.

Value

A list containing two arrays containing the pseudovalues and the jackknife FOM values of the datasets (a third returned value is for internal use).

Note

Each returned array has dimension c(I,J,K), where K depends on the FOM: K1 for FOMs that are based on normal cases only, K2 for FOMs that are based on abnormal cases only, and K for FOMs that are based on normal and abnormal cases.

Examples

result <- UtilPseudoValues(dataset05, FOM = "wAFROC")$jkFomValues[1,1,1:10]
result <- UtilPseudoValues(datasetX, FOM = "wAFROC")
