Simulated ROI dataset

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

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 [1:2, 1:5, 1:90, 1:4], ratings of non-lesion localizations, NLs

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

  • rating$LL_ILNA, this placeholder is used only for LROC data

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

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

  • lesions$weights, num [1:40, 1:4], weights (or clinical importances) 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 [1:2] "1" "2", modality label(s)

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