FitCorCbm; seed = 123datasetBinned123.RdA binned dataset suitable for analysis by FitCorCbm. It was generated by
DfCreateCorCbmDataset by setting the seed variable to 123. Note
the formatting of the data as a single modality two reader dataset, even though
the actual pairing might be different, see FitCorCbm. The dataset is
intentionally large so as to demonstrate the asymptotic convergence of ML estimates,
produced by FitCorCbm, to the population values. The data was generated
by the following argument values to DfCreateCorCbmDataset: seed = 123,
K1 = 5000, K2 = 5000, desiredNumBins = 5, muX = 1.5, muY = 3, alphaX = 0.4,
alphaY = 0.7, rhoNor = 0.3, rhoAbn2 = 0.8.
