Local preferences, dispersion and first diagnoses
Mind map of chapter 21: mono-criterion reading of the material — score gaps Δ_i = E(L_p, C_i) − E(L_d, C_i), sets 𝒢_p / 𝒢_d / 𝒞, dispersion and box plots on matrices M_d and M_p, smoothed profiles on four salient criteria, variants (indifference threshold, histograms, local weighting).
