Power for bounding test with n_+,min = n₁ and n_+,max = ∞ as a function of γ = λ₂/λ_2,0 for tortuosity differences among p = 4 brain regions with ${\alpha }_{\mathrm{t}}=\frac{0.05}{6}$, P_t = 0.90, C_* = I₃, β_* = V′_T β, and ${\sigma }_0^2={\lambda }_{2,0}=(\frac{0.0686}{3})$. Fixed design with n₀ = 18: · · ·; IP bounding with n₁ = 9; – – –; IP bounding with n₁ = 18: ----.
