BayesianFROC (version 1.0.0)

ddddddd: Multiple reader and 2 modalities data such that all modalities have same AUC.

Description

This is a subset of dataList.Chakra.Web.orderd

Details

The author made this dataset to validate the scheme of Bayes factor well works in our Bayesian FROC models

This dataset is made for validation that wheter Bayes factor well work which is a subset of data dataList.Chakra.Web.orderd

dddddd$M

2 modalities of almost same AUC

dddddd$C

3 Confidence levels

dddddd$Q

2 readers

If Bayes factor admit the null hypothesis that all modality are same, that is, 1-st and 2-nd modality of dataList.Chakra.Web.orderd are same, then, the Bayes factor well works.
