Performance plots


  1. Comparison of performance of PPfold(20) and Carnac(20). Positive Predictive Value (PPV) is plotted against sensitivity. Each dot represents a single test of each method. See tables below for raw data (individual counts for PPfold(20) and Carnac(20)).

  2. Comparison of average Matthews Correlation Coefficients (MCCs) for PPfold(20) and Carnac(20). The whiskers correspond to 95% confidence intervals (CIs). 'n' denotes the number of MCCs used to calculate average MCCs and CIs. See tables below for raw data (individual counts for PPfold(20) and Carnac(20)).
