Corner plot showing the marginal distributions (diagonal panels) and pairwise correlations (off-diagonal panels) of the parameters (Y_Eu,r, α, [M_l, M_u], τ) for the (Eu-Zr) Pareto models. Dashed yellow lines mark the parameter values of the model closest to the ideal point (0, 0) in the objective space, with the corresponding numerical values reported above each marginal distribution, and the yellow star marks its position in each correlation plot.
