WebMay 30, 2024 · Feldman and Cousins have developed a method Feldman:1997qc to compute confidence intervals that has well-defined frequentist coverage. Their method has certain advantages over the classical approach to compute confidence levels: it avoids the so-called “flip-flopping” because it offers a natural transition between upper (or lower) … WebMar 20, 2024 · An importance sampling method for Feldman-Cousins confidence intervals.
