What is the likelihood function, and how is it used in particle physics?
What is the likelihood function, and how is it used in particle physics? In statistical data analysis, “likelihood” is a key concept that is closely related to, but crucially distinct from, the concept of “probability”, which is often a synonym in everyday English. In this article, I first lay some necessary foundations for defining likelihood,
