Fig 4. Marginal posteriors for parameters of the setpoint function Pτ(t) (e.g., p0) for (A) Navajo Nation, (B) Arizona, (C) Colorado, (D) New Mexico, and (E) Utah for the time period January 21, 2020, to September 14, 2020.

Recall that Pτ(t) denotes the fraction of the population practicing disease-avoiding behaviors at time t. The value of Pτ(t), a step function, is determined by one or more setpoint parameters, denoted p0, p1, etc. The Navajo Nation setpoint function parameter has the following maximum a posteriori (MAP) value: p0 = 0.35. The Arizona setpoint function parameters have the following MAP values: p0 = 0.60 and p1 = 0.5. The Colorado setpoint function parameters have the following MAP values: p0 = 0.47, p1 = 0.27, and p2 = 0.11. The New Mexico setpoint function parameters have the following MAP values: p0 = 0.34, p1 = 0.19, and p2 = 0.05. The Utah setpoint function parameters have the following MAP values: p0 = 0.43, p1 = 0.35, and p2 = 0.21 For each region of interest, the NPI switch times, τ = {τ1, …,τn}, are indicated in Fig 3.
