Performance plots


  1. Comparison of performance of IPknot 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 IPknot and Carnac(20)).

  2. Comparison of average Matthews Correlation Coefficients (MCCs) for IPknot 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 IPknot and Carnac(20)).
