Binned dataset suitable for checking FitCorCbm; seed = 125

Description

A binned dataset suitable for analysis by FitCorCbm. It was generated by DfCreateCorCbmDataset by setting the seed variable to 125. Otherwise similar to datasetBinned123.

Usage

datasetBinned125

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, 1:2, 1:10000, 1] ratings of non-lesion localizations NLs

• rating$LL num Array[1, 1:2, 1:5000, 1] ratings of lesion localizations LLs

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

• lesions$perCase int Array[1:5000], number of lesions per diseased case

• lesions$IDs num Array[1:5000, 1] , numeric labels of lesions on diseased cases

• lesions$weights num Array[1:5000, 1], weights (or clinical importance) of lesions

• descriptions$fileName chr "datasetBinned125", base name of dataset in 'data' folder

• descriptions$type chr "ROC" the data type

• descriptions$name chr "SIM-CORCBM-SEED-125", 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" modality label

• descriptions$readerID chr Array[1:2] "1" "2", reader labels
