“…Entire fuzzy-binomial options pricing models up (u) and down The fuzzy random binomial option pricing literature provides two approaches to calibrate fuzzy up and down moves u (𝑢 ̃) and d (𝑑 ̃). The first way consists of supposing that 𝑢 ̃ and 𝑑 ̃ are estimated by experts' judgments independently (Muzzioli & Torricelli, 2004;Muzzioli & Reynaerts H., 2007;Liao & Ho, 2010;Shine Yu et al, 2011;D'Amato et al, 2019;Shang et al, 2020;Meenakshi & Felbin, 2019;Wang et al, 2022, i.e., 𝑢 ̃ and 𝑑 ̃ are not connected quantifications or, alternatively, fitting a symmetric increase/decrease rate 𝑎 ̃ in such a way that 𝑢 ̃= 1 + 𝑎 ̃ and 𝑑 ̃= 1 − 𝑎 ̃ (Buckley & Eslami, 2007, 2008. In this last case, 𝑢 ̃ and 𝑑 ̃ are connected by the rate 𝑎 ̃.…”
