Simulated ROI dataset

Description

TBA Simulated ROI dataset: assumed are 4 ROIs per case, 5 readers, 50 non-dieased and 40 diseased cases.

Usage

datasetROI

Format

A list with 3 elements: $ratings, $lesions and $descriptions; $ratings contain 3 elements, $NL, $LL and $LL_IL as sub-lists; $lesions contain 3 elements, $perCase, $IDs and $weights as sub-lists; $descriptions contain 7 elements, $fileName, $type, $name, $truthTableStr, $design, $modalityID and $readerID as sub-lists;

• rating$NL num Array[1:2, 1:5, 1:90, 1:4] ratings of non-lesion localizations NLs

• rating$LL num Array[1:2, 1:5, 1:40, 1:4] ratings of lesion localizations LLs

• rating$LL_IL NA This placeholder is used only for LROC data

• lesions$perCase int Array[1:40], number of lesions per diseased case

• lesions$IDs num Array[1:40, 1:4] , numeric labels of lesions on diseased cases

• lesions$weights num Array[1:40, 1:4], weights (or clinical importance) of lesions

• descriptions$fileName chr "datasetROI", base name of dataset in 'data' folder

• descriptions$type chr "ROI" the data type

• descriptions$name chr "SIM-ROI" the name of the dataset

• descriptions$truthTableStr NA truth table structure

• descriptions$design chr "FCTRL-X-MOD", study design factorial dataset

• descriptions$modalityID chr Array[1:2] "1" "2", modality label(s)

• descriptions$readerID chr Array[1:5] "1" "2" "3" "4" ..., reader labels
