The function computes the critical constants defining the uniformly most powerful test for the problem σ ≤ 1/(1 + \varepsilon) or σ≥ (1 + \varepsilon) versus 1/(1 + \varepsilon) < σ < (1 + \varepsilon), with σ denoting the scale parameter [\equiv reciprocal hazard rate] of an exponential distribution.
