UtilMeanSquares {RJafroc}

Calculate mean squares for factorial dataset

Description

Calculates the mean squares used in the DBM and ORH methods for factorial dataset

Usage

UtilMeanSquares(dataset, FOM = "Wilcoxon", FPFValue = 0.2, method = "DBM")

Arguments

dataset

The dataset to be analyzed, see RJafroc-package.

FOM

The figure of merit to be used in the calculation. 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.

method

The method, in which the mean squares are calculated. The two valid choices are "DBM" (default) and "OR".

Details

For DBM method, msT, msTR, msTC, msTRC will not be available if the dataset contains only one treatment. Similarly, msR, msTR, msRC, msTRC will not be returned for single reader dataset. For ORH method, msT, msR, msTR will be returned for multiple reader multiple treatment dataset. msT is not available for single treatment dataset, and msR is not available for single reader dataset.

Value

A list containing all possible mean squares

Examples

UtilMeanSquares(dataset02, FOM = "Wilcoxon")
UtilMeanSquares(dataset05, FOM = "wAFROC", method = "OR")
