Extreme-value Distribution Analysis of the Second CHIME/FRB Catalog: Assessing the Rarity of the One-off FRB 20250316A
Wen-Long Zhang, Jun-Jie Wei, 2026. The Astrophysical Journal 1002(2), 124.
Generalised extreme-value fits to block maxima of peak flux and fluence in Catalog 2 make FRB 20250316A a strong outlier; with three other outliers removed, the fluence distribution has a finite upper bound that the burst far exceeds.
What it's used for here
A test of whether the brightest one-offs are a distinct class or the tail of one distribution.
