From: Assessment of reproducibility of cancer survival risk predictions across medical centers
Box plots of the correlation coefficients between risk scores of Moffitt Cancer Center (MCC) test data predicted by the models developed from the Moffitt and Vanderbilt data using re-sampling techniques based on 1,000 repetitions. For each statistical model, three correlations are computed: 1) ρ1 (model transferability): consistency of risk scores developed from the VMC and MCC centers, 2) ρ2 (signature transferability): consistency of risk scores predicted by two centers using the same MCC signature, and 3) ρ3 (signature transferability): consistency of risk scores predicted from MCC data using different signatures.
