Figure 2. ln(s_i) as a function of i in three HRFMs with length n = 200. Left: λ₀ = 0.4 and λ₂₀₀ = 1.

Here λ₀ is rate limiting and thus the sensitivities of sites close to site 1 are larger. Note that ln(s_i) decays linearly with i. Middle: λ₀ = λ₂₀₀ = 1. Here the maximal sensitivity is with respect to λ_n/2 and it decreases as we move towards the edges of the chain. Right: λ₀ = 1 and λ₂₀₀ = 0.4.
