What is a LDE?

Answer 1

A LDE, or Large Deviation Estimate, refers to a concept in probability theory and statistics that deals with the probabilities of rare events deviating significantly from the expected outcome. It provides tools to analyze the behavior of random variables in situations where traditional laws of large numbers and central limit theorems may not apply. Large deviation principles help quantify how the probabilities of such deviations decrease exponentially as the sample size increases. This framework is useful in various fields, including statistical mechanics, finance, and information theory.
