WebSep 19, 2024 · A standard approach is through the Gartner-Ellis theorem. Letting { Y n } be a sequence of random variables, not necessarily i.i.d., you let M n ( t) = log E ( e t Y n) be the log-mgf of Y n, and apply the scaling M ( t) = lim n → ∞ 1 n M n ( n t). If this limit exists, then the convex conjugate R ( s) = sup t s t − M ( t) WebAbstract A generalization of the Gartner-Ellis theorem for arbitrary random sequences is established.
