Fitting of the interval distribution with a Weibull distribution. (a) Determination of the optimal log-rank cutoff \(\hat{n}^{*}\). (b) Empirical CCDF of interval Δτ (symbols) and the Weibull distribution with the estimated parameters (lines). The cutoffs \(\Delta\tau_{u}\) and \(\Delta\tau_{u}^{\prime}\) are obtained from the optimal log-rank cutoffs \(\hat{n}^{*}\) and \(\hat{n}^{*\prime}\), respectively
