Motivated by the pricing of lookback options in exponential Lévy models, we study the difference between the continuous and discrete supremums of Lévy processes. In particular, we extend the results ...

In this paper we estimate 𝑅 = P{𝑋 < 𝑌} when 𝑋 and 𝑌 are independent random variables following the Peng-Yan extended Weibull distribution. We find maximum likelihood estimator of 𝑅 and its ...

Recently, Professor Akshit Sinha and his team from the University of Cambridge revealed the potential of large language models (LLMs) in executing complex tasks, even though single-step accuracy has ...
