Results of the bivariate analysis: Bayesian predictive surface by contours at different credibility levels. a Display of the predictive accuracy for each of 21 prognostic models. Each circle identifies the true positive rate vs. the false positive rate of each model. Different colors are used for different techniques and different sizes for sample sizes. b–f Bayesian predictive surface by contours at different credibility levels for the technique of “EEG: tasks”, “EEG: resting state”, “fMRI: tasks”, “fMRI: resting state”, and “Hybrid model”, respectively
