Convergence, sampling and total order estimator effects on parameter orthogonality in global sensitivity analysis
Fig 5
Total order Sobol indices ST of the arterial compliance Csa for the 1-chamber model with continuous measurements.
Panels A—T show ST of Csa, for 3 continuous measurements—left ventricular pressure, systemic arterial pressure and the left ventricular volume (represented in blue, yellow and green curves, respectively), over a single cardiac cycle with differing estimators and sampling methodologies. Measurements are evaluated with N = 10, 000 samples, using B = 1000 bootstrapped samples to evaluate the uncertainty of the estimate. The bands represent 95% confidence intervals associated with specific indices displayed as solid curves.
