Figure 3: Robustness of fitting.
From: A pairwise maximum entropy model accurately describes resting-state human brain networks

In panels (a–d) solid and dashed lines represent the results for the DMN and FPN, respectively. (a) Distributions of the preprocessed resting-state fMRI signals. (b) Relationships between the estimation reliability for the pairwise MEM (equation (3)) and the threshold for binarization. (c) Relationships between the accuracy of fitting for the pairwise MEM (equation (2)) and the threshold for binarization. (d) Dependence of the accuracy of the fitting for the pairwise MEM on the number of regions. Symbols:average, Error bar: s.d. For example, there are 220 different sub-networks (combinations) of N=3 regions for the DMN. (e,f) Scattergrams of the interaction weights obtained from the pairwise MEM fitted to the data for participants no. 1–3 and those obtained from participants no. 4–6 show that the results do not vary by subject.
