Example Morbidity Dissimilarity Indices (MDI) for four configurations. MDIs were drawn for $({\sigma }_1^2/{\sigma }_2^2,\rho )$ equal to (1, 0), (3,0), (1, 0.75), and (3, 0.75) in panels a), b), c), and d), respectively, where ${\sigma }_1^2=\mathit{\text{Var}}({\beta }_1)\text{ and }{\sigma }_2^2=\mathit{\text{Var}}({\beta }_2)$ and ρ is the correlation between β₁ and β₂. Different values of correlations (ρ) effectively alter the angle between the axes, as shown in panels c and d. The solid and dashed contours display the set of all (β₁, β₂), that yield MDI equal to 0.5 and 1.0, respectively.
