Fig. 3From: On the practical identifiability of a two-parameter model of pulmonary gas exchangeContour plot of objective functions (SSE) with logarithmic scale. log(SSE) was plotted with respect to parameters fs and fA. Left SSE for simulated data set no. 5. The global minimum was located at {f s , f A } = {0.1, 0.7}, the parameter values set for data generation. Right SSE for real patient data Pat R1. Global minimum was located at {f s , f A } = {0.17, 0.6}Back to article page
